Assuring correct null-terminated gchar** and profile matching

When testing the patch a bit more I noticed that now that the array is null-terminated it contains one more element that needs to be subtracted when comparing the amount of displays in a profile and the ones that are currently connected.

Now I have extended the patch in this direction and from my point of view it's ready to merge. Feel free to give it a last try with both saving profiles or just retaining the default settings.
