Fix another older bug where the title of a window will not be updated after moving it to another monitor.
In onWindowMoved, when moving an orphan window to the display of the current bar, that window should no longer be an orphan.
This seems to be an old bug that has been made visible with the new workspace taskbars feature.
Sometimes, when closing a window and re-opening a window of the same program, hyprland reuses the window address. Since m_orphanWindowMap was not being cleaned up on window close, the new window would not be updated properly.
