Some visual refresh issues after bumping an event's date to another month
I was in month view, where I had an all-day event set to calendar "foo" today, I opened its edit dialog and bumped it to the next month by simply changing the "08" in "2017-08-27" to "09".
In month view, the event change did not occur until I switched to the other month, otherwise it was still showing up in front of me in August, not telling me the transaction had been completed successfully.
When switching to week view afterwards, the event was still showing up in the wrong week (as being today), even if I moved forward/backward in time with the arrows. Using the "Synchronize" action didn't solve it. I think it solved itself when I folded/unfolded the all-day events' expander at the top of the week view, or maybe I had to restart the app.
