Includes a basic test of the clone and update cases.

Now uses sha1 checksums following merge of 9688.
Also I undid the changes I made to fetch.py
win_template.py now uses conn.shell.has_trailing_slash and
conn.shell.join_path
updated integration tests.

They're not being run by default so make sure they're ready to show

Fixes #9663

Now that we have all of the postgres db being blown away the package manager is initializing a new db.

We don't need to do it manually anymore

- make sure it calls itself correctly, now passes same params as it recieves
- vars is reserved, changed for templatevars to avoid confustion
- forcing mustaches again since the removal broke 'listification' as per #9622
- fixes incorrectly successful tests using undefined var, now it is defined
- now returns empty list if items is None to avoid errors

This test covers a recently fixed bug,
