Reverting the revert that supposedly broke waterfall tests here:
https://build.chromium.org/p/chromium.linux/builders/Android%20Tests%20%28dbg%29/builds/44127/.
However, successive builds:
* https://build.chromium.org/p/chromium.linux/builders/Android%20Tests%20%28dbg%29/builds/44128/
* https://build.chromium.org/p/chromium.linux/builders/Android%20Tests%20%28dbg%29/builds/44129/
passed *without* containing the revert commit, which means our original commit most likely was
not the root cause of the broken tests in the first place.
