Evan Morikawa cd9ccd85e2 refactor(DB): promisify database
Summary:
WIP. The app launches and works for me. I still need to fix the tests
just the DB ones though :D

I changed the `DatabaseProxy` into a `DatabaseConnection` object. It will
request a fully instantiated databse from the backend Browser.

If we're already setup, it'll connect straight to the existing DB.

If we're not setup, then it'll create a new database and run the inital
schema migration on it. The `_createNewDatabase` promise won't resolve
until the migration has run.

Until we add in a more sophisticated migration system and get rid of the
stupid `modelClassMap` that's shoved in `Utils`, I'm passing in a series
of `_setupQueries()` to get everything started.

The `DatabaseConnection` is also the one responsible for queuing up
queries until the DB is fully populated and ready to go.

We actually get a lot of queries before we're setup because a lot of
Stores will make DB requests on `require` in their `constructor` or `init`
methods. (remember all the times we call `_populateStore` in `init`).

Now those queries are aggregated by the `DatabaseConnection` and then
executed sequentially.

Our methods like `persistModel` now resolve only after both the queries
have completed AND their corresponding `triggerLater` has completed as
well.

Test Plan: in progress
