Wayfire (the latest git version) crashes when "send_win_left/right" is used without any window other than a sticky one.

To Reproduce

1. Have a sticky window like Conky.
2. Make sure send_win_left and send_win_right are assigned under [vswitch].
3. Open an ordinary window and move it to another workspace by using one of the above shortcuts, so that there remains no ordinary window in the current workspace.
4. Use one of the shortcuts again.

Then, Wayfire crashes

Probable Fix

This change fixed the crash here:
