TEST: Verify Asnych Storage is functioning

Some reports from the field suggest that users are not able to access the offline functionality.
We need to test this before we make recommendations to improve design (such as informing the offiline user of how to update/sync and date of last sync).

### Tests Requested
_all tests should be performed after authenticating on the test device while connected and verifying the below features show data (otherwise there will be nothing to test against)
- [ ] verify login works
- [ ] verify an assigned team appears on Teams Tab
- [ ] verify a preexisting session is viewable and session type can be updated/modified
- [ ] verify a session can be created and attendance set for that session
- [ ] verify after logging off and on again (while not connected) the changes made do appear
- [ ] connect to a Wifi and login again and populate a Session or Teams view so Sync will be performed
- [ ] verify the data appears (after the online sync) in Salesforce or another Coach App user instance
