Package name normalization is not handled correctly

[alex]

For example:

$ caniusepython3 --projects wsgi_intercept
Finding and checking dependencies ...
No handlers could be found for logger "ciu"

You have 0 projects blocking you from using Python 3!

$ caniusepython3 --projects wsgi-intercept
Finding and checking dependencies ...
No handlers could be found for logger "ciu"

You need 1 project to transition to Python 3.
Of that 1 project, 1 has no direct dependencies blocking its transition:

  wsgi-intercept
