Update CLI test_user

Use stubbed decorator instead of unittest.skip decorator to avoid the
need of handling the unittest import.

Wrap all factories call with a try/except block.

Update test_negative_delete_user_1 because now make_user factory does
not return the password.

Use unicode when searching for a user as the login may contain unicode
characters.
This is the relevant change on this PR, now CLI factories returns what the info command returns and the password for obvious reasons is not displayed.
