Fixed potential progress state stack corruption due to possible exceptions in open process.
We use context managers now to undo any progress state stack modifications.
I blindly converted the code, so its logic should be exactly the same as before - just more safe. I have not understood some code in cate.core.ds.XcubeProgressObserver and to me it seems wrongly implemented. Need to clarify in another PR.
