Removing individual patient update to CQM results

Previously, when a new record was uploaded, we would try to update
all calculation results for just that patient. This code now updates
the record and wipes out all caches. It appears that most popHealth
users upload records in bulk, so individual updates don't make much
sense.

Additionally, some places where collections are cleared, the method
for doing that has been switched from all.delete to delete_all.

This needs to be set at the root of the server to make sure that you
don't just hit an anchor on the page.

Allow popHealth to run when not in a git repository

popHealth has code that will check the .git directory for information
about the latest commit and tag. This change will now display
"Unknown" when there is no .git directory. It should also handle the
situation where tags may not be present (this seems to be the case
when testing on Travis CI).
