Improve ordering of mount action cards

The current implementation of the ordering of mount action cards says that the unmounts are above (so more up to date) then the mounts. This scenario however only makes sense for the setting in that the mount & unmount belong to each other. If they don't (so we have a new mount right after the unmount), we want to have the mount to be on the more up to date position (so more up in the list).

This affects the sorting for:

• configuration actions > mount actions
• device actions > mount action
• platform actions > mount action
