Review comment:
Thanx @adoroszlai for the fix, I am able to repro this, changes seems
fair enough.
Does it makes sense to `removeGroup` explicitly in case
`server.isExist(pipelineId)` is true, rather than waiting? Might speed up test?
We can ignore the exception from `removeGroup` in the wait and retry to counter
the race condition
