[backup/restore] Binding installations are not restored from backup

[tlc76]

Expected Behavior

openhab2 backup/restore scripts should save entire openhab2 configuration

Current Behavior

Bindings are not restored (no bindings appear "installed" after a restore performed on a fresh openhabian/openhab2 installation). As a consequence, all things are found in "Uninitialized" state.
The issue is resolved by:

• manually installing the bindings from Paper UI
• restarting openhab2 service (sudo service openhab2 restart)
• result: things are now fully functional, in "Online" state

Steps to Reproduce (for Bugs)

1. backup performed on raspbian pi, openhab2 version 2.2
2. script used: $OPENHAB_HOME/runtime/bin/backup
3. fresh installation of openhabian on a different sd card
4. $OPENHAB_HOME/runtime/bin/restore performed from the backup archive saved at step 1 on the fresh openhabian os

Context
