Clean up test database after tests

Fixes #1064

- Updated grunt config for unit and functional tests to remove the test
database after each is run.
- Cleaned up a couple of issues with the functional tests that may have
been causing travis builds to fail randomly, including: the start page
is now `about:blank` instead of whatever page the last test suite left
off at, added some checks in the logout tests to ensure they're truly
independent of the other test suites.

Fix style issue on user-image on Firefox and Opera

On both Firefox and Opera (OSX) the user image badge in
the settings page wasn't displayed.
Also, on firefox the badge overlay didn't have the proper size.

I don't know if there's a specific use case requiring a `display:
table` instead of a plain `display: block` but that was failing on
Firefox and Opera.

Using a block instead seems works perfectly (at least on Opera, Chrome,
Safari, Safari Mobile IOS7 and Firefox) regarding the badge size issue.

On Opera, though, the border radius wasn't applied properly to the
image. Adding a `border-radius: 100%;`fix that.

Fix notification bug

The date stored in the model is in a different format and needs to be converted before being checked. Otherwise, any blur event will trigger the notification that the date has been changed, even if the date is the same.
