waitUntilDone returns non done status when timeout is exceeded

[sverhoeven]

When job takes longer than 5 seconds calling scheduler.waitUntilDone(jobId, 5000) will result in a status object which is not yet done (status.isDone() == false).
I did not expect this, I expected waitUntilDone to either return a done status or a TimeoutException.

Same goes for the waintUntilRunning method, it also returns a non running status when timeout is exceeded.

All schedulers which use the waitUntil* implementation in nl.esciencecenter.xenon.adaptors.schedulersScriptingScheduler have this problem.
