* Fix Profile Editing again (IOS-239, #1244)
This needs a bit of explanation, I guess, so please don't squash if possible? I didn't take into consideration, that the `ProfileViewController.viewModel` changes. And when it changes, all the combine-connections just ... disappear. This PR changes that (but probably I oversaw something again).
* Disable pull to refresh for editing mode (IOS-239)
* In case of nothing change, cancel editing (IOS-239)
