[Orleans 7] Orleans runtime fails to start when grain interface contains generic array constraint

[n-sidorov]

When Orleans encounters grain interfaces with generic array constraint it fails to start.

Example of interfaces:

public interface IGrainGeneric<T>
{
}

public interface IGrainArray<T> : IGrainGeneric<T[]>, IGrainWithStringKey
{ 
}

Example of error from trying to run TestCluster:

Message: Class Initialization method <omitted> threw exception. System.InvalidOperationException: System.InvalidOperationException: Encountered unexpected character. Expected '[', actual ']'..

Stack trace from failing TestCluster:
