parser: Don't create reference in xmlLookupGeneralEntity

Browse Source 
This should only be done in xmlParseReference.

The handling of undeclared entities is still somewhat inconsistent. In
element content we create references even if entity substitution is
enabled. In attribute values undeclared entities are always ignored.
