Incorrect(?) sanity check in DynamicSignal.cs

I may have found a clerical mistake in DynamicSignal.cs, line 406 ...

Before emitting a signal, there is a sanity check that makes sure the passed args have the correct type for the signal.

If an arg's type matches exactly, everything is fine. If an arg's type is a subclass of the expected type, an exception gets thrown; I don't think this is intended?

Shouldn't it be something like this?
