Recent pylint versions warn against the use of an 'else' in a 'try-except' block if using a 'return' on the 'except' part is is the idom used by ansible-freeipa when retrieving IPA data objects. This change removes the usage of the 'else:' in such cases, and modify the templates so that new modules do not have the same issue in the future.
