    Crash when exporting record selectors of data family instances
    
    This fixes bug #294.
    
    This also fixes a related but never-before-mentioned bug about the
    display of GADT record selectors with non-polymorphic type signatures.
    
    Note: Associated data type constructors fail to show up if nothing is
    exported that they could be attached to. Exporting any of the data types
    in the instance head, or the class + data family itself, causes them to
    show up, but in the absence of either of these, exporting just the
    associated data type with the constructor itself will result in it
    being hidden.
    
    The only scenario I can come up that would involve this kind of
    situation involved OverlappingInstances, and even then it can be
    mitigated by just exporting the class itself, so I'm not going to solve
    it since the logic would most likely be very complicated.
