[rygel/wip/ruih] ruih: Allow null for protocols

[Jens Georg <jensgeorg src gnome org>]

commit 4209478c926c06375a2248b8daead17412a16eb4
Author: Jens Georg <mail jensge org>

    ruih: Allow null for protocols
    
    The code checks for == null and returns true then. But if the variable
    is not marked as nullable, vala will add g_val_return_if_fail (FALSE,…
    to the beginning of the function.
