Edited Issue: CompareAttribute does not use custom error messages [1401]

__Scenario:__
User likes to customise/localise the error message for the Data Annotations CompareAttribute in a view model.

__Issue:__
When the Data Annotations Compare attribute (System.ComponentModel.DataAnnotations.CompareAttribute) is used with custom error messages, the custom error messages are never shown, instead the default error message is always shown.

Example model:
```
private class ExampleModelWithCustomErrorMessage
{
[Compare("OtherProperty", ErrorMessage = "Custom error message")]
public string MyProperty { get; set; }

public string OtherProperty { get; set; }
}
```

same issue with error message from a resource, i.e.

```
private class ExampleModelWithCustomErrorMessageFromResource
{
[Compare("OtherProperty", ErrorMessageResourceType = typeof(Resource.Resource), ErrorMessageResourceName = "ResourceKey"))]
public string MyProperty { get; set; }

public string OtherProperty { get; set; }
}
```

The above examples will both print the default error message _'MyProperty' does not match 'OtherProperty'_.

__Reason:__
CompareAttributeWrapper in CompareAttributeAdapter does not copy over the custom error message properties when creating a new, wrapped CompareAttribute.

New unit test in CompareAttributeAdapterTest.cs:
```
[Fact]
public void ClientRulesWithCompareAttribute_ErrorMessageCanBeCustomised()
{
// Arrange
const string expectedErrorMessage = "Computer says no";
var metadata = ModelMetadataProviders.Current.GetMetadataForProperty(() => null, typeof(PropertyNameModel), "MyProperty");
var context = new ControllerContext();
var attribute = new System.ComponentModel.DataAnnotations.CompareAttribute("OtherProperty")
{
ErrorMessage = expectedErrorMessage
};

var adapter = new CompareAttributeAdapter(metadata, context, attribute);

// Act
var rules = adapter.GetClientValidationRules()
.OrderBy(r => r.ValidationType)
.ToArray();

// Assert
ModelClientValidationRule rule = Assert.Single(rules);
Assert.Equal(expectedErrorMessage, rule.ErrorMessage);
}
```

Here is also an attempt at fixing the issue (CompareAttributeAdapter.cs:37)
```
public CompareAttributeWrapper(DataAnnotationsCompareAttribute attribute, ModelMetadata metadata)
: base(attribute.OtherProperty)
{
ErrorMessage = attribute.ErrorMessage;
ErrorMessageResourceType = attribute.ErrorMessageResourceType;
ErrorMessageResourceName = attribute.ErrorMessageResourceName;

_otherPropertyDisplayName = attribute.OtherPropertyDisplayName;
if (_otherPropertyDisplayName == null && metadata.ContainerType != null)
{
_otherPropertyDisplayName = ModelMetadataProviders.Current.GetMetadataForProperty(() => metadata.Model, metadata.ContainerType, attribute.OtherProperty).GetDisplayName();
}
}
```
