Regression: ASP.NET Core 1.1 RC Action Selection

[commonsensesoftware]

Symptoms

Some routes no longer match correctly to the expected actions after the 1.1 release candidate.

Triage

Changes to the implementation of the IActionSelector addressed issues related to route constraints, but cause certain other routes to be ambiguous when they shouldn't be. For example, /v1/resources/{id}
and /v1/resources/search are now considered ambiguous because the value search can be substituted for the {id} route parameter.
