Fix crash selecting custom asset preview from maximized File Browser

If Preferences > Interface > Temporary Editors > File Browser is set to
"Maximized Area", "Load Custom Preview" in the Asset Browser would crash
after selecting the file.

1e799dd26ec1e848 was important to get this issue fixed. This commit just
ensures the file-list is recreated correctly after closing the temporary
File Browser, so the custom preview operator can execute on valid
context.
