Remove #noqa from gettextutils imports

Removed #noqa from gettextutils and added them to import_exceptions.
I think it is better to specify option in one place (tox.ini) than
every time take care that you do not forget to specify this tag.

Also removed a few unused imports that were revealed in the process.
