Fixes browser_tests with --enable-text-input-focus-manager enabled.

http://crrev.com/173803002 introduced WebView::NotifyMaybeTextInputClientChanged, but the CL missed some cases.  We should be aware of more cases that the underlying web_contents may change.
- When an interstitial page is attached / detached
- When the render process is gone

browser_tests are broken with these cases when --enable-text-input-focus-manager enabled.  This CL fixes the broken tests.

BUG=290701
TEST=Run browser_tests with --enable-text-input-focus-manager enabled.
