Caused by [0] which closed all popups when adding a file selector event.
This was done so pressing "Open..." from the splash closes the splash
however it caused BUTTONS_OT_file_browse & BUTTONS_OT_directory_browse
to crash when changing the path of an RNA property within a popup.
Move the logic to close popups into the splash screen itself.
Since some actions such as opening a URL's should keep the splash open,
resolve by closing the splash when a file selector is opened.
