[pygobject] Don't use GI type for determining pointer extraction from GValues

[Simon Feltman <sfeltman src gnome org>]

    Don't use GI type for determining pointer extraction from GValues
    
    Replace usage of g_type_is_a() with G_VALUE_HOLDS() when extracting
    pointers from GValues being marshalled from properties and signals.
    This fixes fallout from commit abdfb0f.
