Remove Outdated Upgrade Check

This check was for pre-rewrite versions of the application. It forced a
sync against the website. Unfortunately, it causes duplicate sync
processes on new installs. Possibly, it also contributes to a NPE on
Android 3.x devices. (See issue #40)
Try to Recreate mManager if it is Null

In some cases on Android 3.x, mManager is null for the record tasks.
This will attempt to re-create the object if this is the case.

Fixes #40
