networkException 64c66e26f5 LibGUI: Check if event loop is alive before quitting it in Dialog::close ...

Previously we would quit the event loop of a dialog without checking if
it is still alive in the Window::close overload. This patch updates the
implementation to make use of the existing done method, handling closes
more gracefully.

This fixes a CommandPalette crashing when opening an about dialog, as
since 1074c399f3 the command palette
dialog would handle a WindowBecameInactive event after closing itself
due to the action already being called.
