Subject: [PATCH 16/24] test: improve aux teardown

Handle the case of device teardown where the first pass
could have only a single, but opened device, for removal.
In such case we want to at least once go through
the udev_wait and retry removal again.

TODO: maybe a sleep .1  might be usable as well with udev_wait
