UI: Set correct window title for fullscreen projector

Before this change, opening up a fullscreen projector would have the
wrong window title (Windowed Projector). This was because the call to
update the window title was called before a monitor is set, and the
title is determined by whether a monitor is set.

This change moves the update title call to after the geometry or monitor
gets set, ensuring the window title is correct.
