I think we usually put

above functions like this.

Done.

We shouldn't allow this on a null tab.  We should check that in java land.

Done.

what happens if this isn't called?

Should this class actually hold the web_contents ref itself (and add itself as
an observer for it's destruction) to ensure this will always happen.

That also goes along with my other comment about a consistent way for getting
the URL from the webcontents.

[qinmin, 2015/03/17 23:49:30]

Not necessary. 
InfoBarService is already a WebContentsObserver, and it will remove the infobar
for us if WebContents is gone.
