backing up a single entry didn't get a refresh.
Additionally, I had a case where something wasn't refreshed because two refreshes were running in parallel (I tried to change this, but a Java Thread cannot be stopped from outside and from inside didn't work either, but that's another story).
Anyways, it doesn't make much sense to start a refresh thread before an action (especially when caching), so I removed this.
All refresh invocations are now at the end of some action.
I also added a TODO, because parallel refreshes only show the spinner while the first one is running, because it is reset after the each refresh (and it is only bool)
