Fix possible NPE in IndexDiff when not all submodules are cloned
The latest changes to IndexDiff just assumed that all configured submodules are allways cloned. If a configured submodule did not exist an exception was thrown. This is fixed by this commit. Bug: 450567 Change-Id: Iabe3b196d998c19483082e5720038ebddaeb1890
