Password policies in pwpolicy-find are now sorted in the expected
numerical manner. Also tweaks one of the unit tests so that it

Always call convert_time_for_output so time gets reported correctly.
That method has its own checks for whether the attributes are present;
an additional check is unnecessary.
Use a key function for sorting; cmp is deprecated, slower and
more complicated.
Add a test
https://fedorahosted.org/freeipa/ticket/2726
Test that `pwpolicy_find --pkey-only` works as expected
Test that deleting a group removes its password policy
Rename the test module to be consistent with other plugin tests.
