Fix file.managed traceback when source is a list

If file.managed state has a source param which is a list, and none of
the URIs in that list are found, a traceback occurs. This commit
modifies salt.modules.file.source_list to raise an exception when source
is a list and no matches are found, and then catches that exception in
the file.managed state so that Salt can return gracefully with a False
result and meaningful error message.
