adevice will now exit if installed shadow apks found on device.

Adevice currently detects installed apks, prints a warning and continues to update.  This could cause issues/be confusing - since adevice does not update those apks but they will ocnitnue to override.

Instead adevice will now print out the commands needed to uninstall the apks and get the device into flashable state and then exit.
