Crash fix when setting a background image by URL. #3077 

When we choose a file from URL we don't get the filename.
In background image apply method we test for a theme / palette
file extensions. Now we don't crash there, but we still can't set
a .tdesktop-theme or .tdesktop-palette file from URL. Who cares :)
