Edited Issue: Adding support for collection of simple types on the default action selector. [322]

Currently if we have the following action, the request below would fail with "Multiple actions were found..." error because the parameters are not simple types so they're not used for disambiguation by the default action selector. For vnext, we can consider adding special support for collection of simple types.

public string Get([FromUri] IEnumerable<long> id)
public string Get([FromUri] IEnumerable<long> campaignId)

Request: GET /api/Test?id=1&id=2&id=3
