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.
