Mike Dalessio 4ffc3fb019 [ruby/rdoc] fix: alias to method with call-seq
This change fixes alias call-seq to return nil if the method's
call-seq does not specify the alias.

Previously, the alias's call-seq would be an empty string in this case
which broke darkfish rendering.

This change also backfills test coverage for 0ead786 which moved
call-seq deduplication into AnyMethod.
