Guake always appears on mouse display regardless of Guake Preferences #1689

Describe the bug

Guake appears on mouse display even though "always on primary" option is checked in Guake Preferences -> Main Window -> Placement -> Appear on display. Same thing happens when "0 (primary)" option is checked. These options seem to have no effect.

Expected behavior

Guake should appear on primary display, as per the checked option in Guake Preferences.

Actual behavior

Guake appears on mouse display regardless of what is checked in Guake Preferences.

To Reproduce

1. Go to Guake Preferences -> Main Window -> Placement -> Appear on display.
2. Toggle each option, one at a time.
3. Use the "Toggle Guake visibility" keyboard shortcut to open Guake.
4. Guake appears on mouse display everytime. The "Appear on display" options in Guake Preferences seem to have no effect on Guake's behavior.
