If for example a tinfoil connection edits the datastore, a subsequent
connection can be "corrupted" by those changes. By setting the parse
status of the caches as False at exit, the behaviour becomes the same
as a newly setup server as a new data store is setup.
This avoids problems in tests when BB_SERVER_TIMEOUT is set as the
server is properly reset between connections.
