homematic: fix backup mv (#2371)

The recent backup fix introduced another error:
mv complains about us trying to move a folder into its own subfolder.
The script then aborts due to set -e. By ignoring the exit code of mv here
we get the desired result (complete backup and no error in ui)

 #### WARNING: This add-on is considered to be obsolete/retired in favor of the much more advanced third-party [RaspberryMatic CCU](https://github.com/jens-maus/RaspberryMatic/tree/master/home-assistant-addon) add-on for running a HomeMatic/homematicIP smart home central within HomeAssistant. If you want to migrate to the new add-on, please make sure to update to the latest version of this old "HomeMatic CCU" add-on first and then use the WebUI-based backup routines to export a `*.sbk` config backup file which you can then restore in the new "RaspberryMatic CCU" add-on afterwards (cf. [RaspberryMatic Documentation](https://github.com/jens-maus/RaspberryMatic/wiki/Installation-HomeAssistant))
