White patch is displayed while rotating device

[Issue]        http://suprem.sec.samsung.net/jira/browse/TWF-2216
[Problem]      White patch is displayed while rotating device
[Solution]     Manually invoke rotation when browsing websites when
               browser receives "rotate,prepared" callback from
               webview.
[Verify]       Open any website, rotate device. Rotation should be
               smooth. Then use other views and check if rotations
               works as intended.
