QIconLoader: reset search paths when theme name is cleared

Browse Source 
When we reset the theme so that icons should be provided by the
system theme, then reset the search paths to the system-provided
paths as well. Otherwise we'll keep looking for the system theme
in user-provided search paths, which can't work.
