Don't error during deploy when there are no .pycs to remove.

During deploy we remove all .pyc files. When I was hacking on the Peep stuff, stage got in a state where there were no .pyc files to remove, and that caused an error, since rm didn't have any arguments. It is possible to get in this state in other ways, mainly in relation to new deploys or broken deploys.

This is the commit that is actually on stage.

quick r?
