Fix instant apps banners immediately disappearing.

Compares the URL the instant app banner was launched on with the current
WebContents URL to ensure we're not mistakenly dismissing banners on the
same page they were launched.

This check occurs before we use the general InfoBar ShouldExpire(),
which was using the NavigationDetails to see if this was the same page,
which is untrue on a redirect.

Fix recently const broken InfoBarDelegate.

InfoBarDelegate's infobar() method was recently made const broken
according to the Chromium C++ Dos and Don'ts guidelines (my bad.)

This fix makes InfoBarDelegate const correct again, and now stores a
reference to the WebContents within the InstantAppsInfoBarDelegate so
we don't need to get WebContents from the info bar using infobar().
