Given the following code, pylint fails with a traceback when it tries to look for not-context-manager error:

#!python

from django.db.backends.oracle.base import DatabaseWrapper as DjDatabaseWrapper

class DatabaseWrapper(DjDatabaseWrapper):

    def _close(self):
        if self.connection is not None:
            with self.wrap_database_errors:
                return self.pool.release(self.connection)

The traceback is:

#!python

UnboundMethod.getattr calls the getattr of its _proxied object.

It previously crashed, since it called super(...).getattr(..) and the first ancestor in its mro was bases.Proxy and bases.Proxy doesn't implement the .getattr method. Closes issue #91.
