Workaround RecentTabs blank issue on certain Samsung devices.

Workaround RecentTabs blank issue on certain Samsung devices.

This was mystifyingly introduced by:
https://codereview.chromium.org/2014433002

It turns out that previously, this relied on calls to setStatusBarColor
based on theme color notifications when nothing changed.  This was
triggering a root level relayout, which hid this issue.

For now, force a root level relayout when attaching the recent
tabs page to the window.
