Add a future for casting complex numbers involving -0.0i to string

The case that is meant to handle this in the _cast function is not executing so
the cast is not handled correctly.

Add a future about unresolved call error for method call that shouldn't happen

record is causing an incorrect unresolved call error.  Making the record
non-generic makes the error go away, as does removing either call to C1.method
or C2.method.
