Adding migrate to load

Previously migrate was only in init. This will still allow crashes due to not migrating if customers call other public methods prior to calling OneSignal initWithLaunchOptions. We should avoid this as best as possible by migrating immediately.

This implementation can be changed later to queue all methods until after init has been called so that we don't unnecessarily migrate.
