Small cleanup of messageStorage/sqlite.

* Extend test coverage to the `search` function.
* Test sort order of messages from `getMessages` and `search`
* Move reversal of `search` results from Vue to messageStorage.
* Remove unnecessary uses of `sqlite.serialize` in tests.
* Return promises from test functions where possible.
