Log Message

Uncaught Exception: TypeError: null is not an object (evaluating 'mouseBlock.addEventListener')
https://bugs.webkit.org/show_bug.cgi?id=190766

Reviewed by Brian Burg.

* UserInterface/Views/NetworkTableContentView.js:
(WI.NetworkTableContentView.prototype._populateWaterfallGraph):
When creating the `mouseBlock`, if the `startTimestamp` and `endTimestamp` are equal, we
don't create an element. If this is true for the total range of the `WI.Resouce` (meaning
its `startTime` and `responseEnd`), don't even try to create blocks.
