Armin Krezović 7dda25b2d5 toytoolkit: Return NULL when no outputs are present 
Currently, display_get_output returns a first member
of the linked list, which can never be NULL.

This is problematic, as the function would return a
dangling pointer and NULL pointer checks wouldn't
work where needed and some of the invalid members
would get accessed that way, resulting in a crash.
