GAS: Fix OSU Providers List response with invalid configuration

Browse source 
If the OSU Providers configuration was invalid (included osu_server_uri
but not osu_method_list), it was possible for the GAS response
generation to hit a NULL dereference. Fix this by checking for the
invalid configuration before trying to fill in the OSU methods.
