Offline fixes (#1080)

* Remove app manifest support

Also update pouchdb to 6.2.0

* Make sure login tests wait until db is loaded to finish.

* Setup testing to use chrome and service worker

* Fixed error when sys admin and not in stand alone mode

* Use worker-pouch to access local db via sw

Also, make sure search works offline

* Move pouch-find-indexes to mixin

* Sync local changes to remote

* Added logic to use background sync to retry remote syncing.

* Change all users to use oauth

Move away from CouchDB sessions so that for offline use we can use
oauth to validate users.

* Remove unneeded logging

* Setup to rely on background sync retrying on failure.

* Make sure logout and login handle offline gracefully.

* Make sure service workers are disabled for Electron.

* Make sure service worker is disabled on Electron tests.

* Try chrome headless

* Try using yarn and chrome beta

* Fix issues logging in with Electron

* Try using chrome beta headless

* pbkdf2 shouldn't need to be specified directly

* Removed unneeded code

* Try to get chrome headless working

* Try upgrading ember-concurrency if that is the issue.

* Fix issues with users DB in standalone (Electron) mode

* Try using regular Google Chrome

* Move back to PhantomJS

* Go back to npm
