Steps to reproduce

1. Create an event
2. Click on the events tab
3. Click show all
4. Reject/approve the announcement

Expected behavior

When the event is rejected/approved all of the events are still shown, like when you initially clicked the show all button

Actual behavior

When the event is rejected/approved, you have to click the show all events button again as they automatically collapse.

Fix: respect any query params (?=...) in the url
