ERP5Type: Assorted cleanups around indexation methods.

Do not check portal's isIndexable, it is checked again in ZSQLCatalog.
Directly bind superclass callable instead of doing an extra getattr +
call.
Trivial python simplifications.
Assorted coding style improvements.
Drop unhelpful comments and docstrings.
