Hide the "Move to other window" menu option when there is only one tab

Hide the "Move to other window" menu option when there is only one tab

If the last tab is moved to the other window and the device has a home
page, the original activity closes, which leads to a weird, confusing
animation. There's not a strong use case for having two windows open
with only one tab.
