Ignore the decl inside the protocol decl.
Before this patch we would fail in the type checker with ambigious symbols to be replaced:
the default implementation and the procotol requirement.
Scope: Affects dynamic replacements of protocol extensions.
Risk: Low. We remove one entry from the found candidates: the protocol
requirement.
Testing: Regression tests.
