Update channel names when retrieving user tasks

Usertasks hold their arguments in an opaque json structure that is not
connected to the other data at the db level. When loading tasks that
holds references (like channels) they could have changed in the
meantime. This is now a hacky way around that updates the channels
when loading. Should they be deleted, the tasks fails when running.
