fix(wm): switch only to different workspaces

Previously a Show event when clicking Firefox tabs would trigger a
refocusing of monitors and workspaces every time for a known hwnd, which
meant that in practice, the tab would be taken out of the current window
and a new window would be created.

This commit ensures that the workspace switch is only done if it would
be to a different monitor/workspace combination.
