Restore additional subtypes when the package is updated

With this CL, Intent#ACTION_MY_PACKAGE_REPLACED will
not only update the visibility of the setup activity but
also reconstruct additional subtypes.

This is important because the system always removes all
the additional subtypes whenever the package is updated.
