Backport #18451
Backport #18447
One of the repeated intermittent failures we see in testing is a failure due to
branches not being ready to merge.
Prior to the immediate queue implementation we would attempt to flush all the queues
and this would prevent the issue. However, the immediate queue is not flushable so
the flushall is not successful at preventing this.
This PR proposes an alternative solution - wait some time and try again up to 5 times.
If this fails then there is a genuine issue and we should fail.

There are a few places where tests appear to reuse testing repos which
causes random CI failures.
This PR simply changes these tests to ensure that cloning always happens
into new temporary directories.
Fix #18444
There is a potential race in the drone integration tests whereby test-mysql etc
will start writing to log files causing make test-check fail.
