Rbarlow test rpms file scheme

This pull request does the following:

1) Remove some stray index.html files that got pulled in when I used wget to recursively retrieve a repository from fedorahosted.org.
2) Remove stray print statements from several files.
3) Convert http:// schemes to file:// when possible in test_rpms.py. This should help us to have fewer Jenkins errors.
4) Fix a test that I found that wrapped the test in a bad try, except, pass pattern.
5) Move the pulp_unittest repository to a more descriptive path so that I can more easily identify and fix other tests that synchronize with it via http.
