kroki/tomash@moonlight.home 68a4db3503 BUG#25211: events_bugs.test fails on sapsrv1
The problem was that the events_bugs test could randomly fail due to
races in the test case.

The solution is to replace fixed sleeps with reliable polling of a
certain state to settle.  For that, a new auxiliary script
include/wait_condition.inc is used, that allows waiting for a given
query to return true.
