feat: Implement device to cloud push for all the files to resolve Murena.io recovery

eDrive checks if a recovery is needed and logs out and logs in the user to delete and recreate its database. Because of the recreation of the database, all the files and (syncable) folders are pushed to cloud storage.

When the process completes, a separate SharedPreference is used to track whether recovery is needed or not. It is done so because if a user logs out and logs in from AccountManager, eDrive's initial preference is cleared. However, this recovery preference will not be cleared unless the user explicitly clears eDrive's data.


In EdriveApplication's onCreate() method, an instance of RecoveryManager initiates the recovery process.

Inside RecoveryManager, it checks whether the recovery is needed using RecoveryPreferences. RecoveryPreferences keeps a separate SharedPreferences which is not cleared when the user logs out and logs in via AccountManager.

For recovery to happen, RecoveryManager logs out and logs in the user consecutively. This process eventually deletes eDrive's database and the default SharedPreferences and then creates them, enabling all the files and folders to be synced again with the cloud.
