ipatests/test_integration/test_backup_and_restore.py: No clean master uninstall

test_replica_install_after_restore is calling tasks.uninstall_master which
is disabling the firewall services for freeipa. The following ipa-restore
call is not reapplying the firewall settings. Calling tasks.uninstall_master
with clean=False will disable the firewall cleanup.
