Multiple API usages on one line result in one TODO comment.

[m-alger]

Say I have a line

chrome.tts.speak(chrome.storage.local.get('something')['something']);`

This will generate one TODO, either

// TODO(Caterpillar): Check usage of chrome.tts.speak.

or

// TODO(Caterpillar): Check usage of chrome.storage.local.get.

Both should be generated.
