Describe the bug

Running bandit on a single source file in the current directory does not seem to work. It produces a warning:

WARNING Unable to find qualified name for module

I am not sure what the warning is trying to achieve?

Reproduction steps

1. $ touch dummy.py
2. $ bandit dummy.py  # produces the warning
3. $ bandit ./dummy.py  # does not produce the warning

Expected behavior

No warning should be produced.
