test: add workaround to prevent a timeout during the server deletion (#…

…513)

When the following steps are executed, the server deletion fails with a
timeout:
- delete primary IP (attached to the server)
- delete server
- timeout after 5 minutes on server delete action


Adding the 2 seconds pause will work around this timeout.
