Sami Makki 98bc1354e2 Remove dead code and use default value of argparse.
In the 'tool' method, the var 'apply_rule' was tested, and the
method returned if it was true. Then, it was tested again even
though it could only be 'false' (or not be None).
Also, an unused parameter of main() had been removed.

Closes-Bug #1650599
