[a-t-0]

If you run:

src/main.sh -ac Orbot,DAVx5 -nu root -np

in here https://github.com/HiveMinds/Collabora-Online/issues this script toggles all the calendars, regardless of whether they were toggled on or off.

• Check for each toggle wether it is set to "on" or not.
• If "on": do not toggle.
• If "off": toggle to on.
