Fix another case of zombie methods.

Summary:
Fix another case of zombie methods. A method was being deleted,
then a new one was being created with the same name/signature. The annotations
from the previous version of the method persisted, causing an assertion to fail.
(The failure only occurred if InlineInitPass was enabled.)
