D7586: remotefilelog: have command wait for background task in the tests

[marmoute (Pierre-Yves David)]

marmoute added a comment.


  For those who wants to see the test misbehaving, your just need to run it in a loop on heavy load:
  `python run-tests.py --runs-per-test 10000 --loop -j 90 test-remotefilelog-bgprefetch.t`
