ansible_freeipa_module: Fix errors in batch mode

The error string returned by execute_ipa_commands in batch mode
additionally contains the whole parameter list for the command. This is
different to non batch mode execution and breaks tests that are checking
the returned error message.

A left over debug message also have been removed from the error
processing.
