[TTS][Overlay] Remove onContentLoadFinished.

[TTS][Overlay] Remove onContentLoadFinished.

OverlayPanelContent#onContentLoadFinished is being called even when
the content was not on the main frame, which is not correct.
Looks like we don't really need this notification anyway.  It
was being called for metrics and to clear out history of error
pages in the unlikely case that GWS returns errors for our
searches when being preloaded.

This CL removes OverlayPanelContent#onContentLoadFinished.
