Failing atomic/batch uploads tests

[rtilder]

test_purgettl_script fails if memcached isn't running, at least with the sqlite backend. Possibly only with the sqlite backend.

test_batch_ttl_update and test_batch_ttl_is_based_on_commit_timestamp are still being skipped. Errors for test_batch_ttl_update seem to indicate that the commit query, at least for sqlite, may not be kosher.

@rtilder it seems to be passing for me now, can you confirm whether this is still an issue?
