gnome-software crashed with SIGSEGV in gs_app_has_quirk()

[Felipe De la Puente]

It happened during an instalation of the googletalk plugin. I think the .deb package is not ready for the new gnome-software? Anyway it shouldn't fatal.

I think a recent change in gnome-software has exposed this. This gs_app_has_quirk doesn't check if app is NULL, where all the other functions do. It's still an error that app is NULL for some reason, but we can workaround this for now.
