File build/android/tombstones.py (right):

https://codereview.chromium.org/1002293004/diff/1/build/android/tombstones.py...
build/android/tombstones.py:51: raise StopIteration
This gets raised anyway, so I removed the explicit raise.

A revert of this CL (patchset #2 id:20001) has been created in
https://codereview.chromium.org/1004803008/ by jbudorick@chromium.org.

The reason for reverting is: Looks like this is causing flaky failures on the
CQ..
