After the last round of changes, I discovered that the new assertion in JField is actually getting 
tripped when a JsniFieldRef is constructed.  To get around this, I initialize the instance field to a 
null literal during a JsniFieldRef's construction.  I also mirrored these changed into JMethod and 
JsniMethodRef.
