Cancel button saves data anyway when adding/removing channel from group

[luckkmaxx]

Steps to reproduce

Edit a channel group.
You can do changes to the name field and if you tap "Cancel" button the name will not be changed.
But if you add or remove channels from the group, the changes are saved anyway after cancelling.

Expected behavior

Cancel both, name and channel list changes

Actual behavior

Only the name field is canceled
