rotate does not work if tab is open

[Egmont Koblinger]

I'm intentionally filing a duplicate of bug 1316573, so that it appears under the Terminator project (https://bugs.launchpad.net/terminator/) rather than just among the Ubuntu packages.

rotate_cw and rotate_ccw only work if no tab is open.
Steps to reproduce:

-open terminator
-split window
-rotate works as expected
-open new tab
-return to previous tab
-rotate does not work

Furthermore, new bug in the gtk3 version: More often than not, the focused pane also loses focus (while its title usually mistakenly stays red, but it turns to gray after the window loses focus and remains gray when the window is focused again).

Change another occurrence of the same pattern in the source. Not sure if it fixes anything, but cannot hurt :D
