v2020.7.1-beta.4 (202007014)

General fixes & optimizations
Backup/restore magisk data's SELinux contexts (ditch the hard-coded `u:object_r:system_file:s0`).
Mark all restored apps as installed from Google Play Store.

WARNING
This version will fail to restore magisk data backed up with previous builds.
Use the backup creator (backed itself up too): `/data/media/migrator/*/migrator.sh`.
