* Fix a few typos
The "database instead of store" change isn't a typo fix, per se, but
these tests are testing the lower-level database layer, and I'm about
to introduce some tests for the higher-level store layer, so I want to
avoid any confusion in the test names
* Start on SQL store-level tests
* Add some tests for createBag
* Add test for getBagTiddler and getBagTiddlers
* Add basic recipe tests
* Add a test for saving a tiddler within a recipe
* Add store test for deleteTiddler
It is now possible to create and edit tiddlers, using the existing tiddlywebadaptor syncing mechanism. There are a lot of hacks and lumpiness to make things compatible, so I think I will end up with an independent implementation
