Commented Issue: The error message for a function import being used in query option should be more specific. [1635]

A function import can not be used in query option, and if it is used, the error message should be specific.

Repro:
1. create a function import
2. use it in a query option such as
~/ConventionCustomers?$filter=GetConventionCustomerNameByIdImport(CustomerId=407)%20eq%20'Name%207'

Expected:
The error messages says the function import GetConventionCustomerNameByIdImport can not be used in query option.

Actual:
