Always unload height fields

Browse source 
loadCell always adds a height field, but unloadCell only removed it for
cells with height data. Reloading a cell overwrote the height field
added earlier (leading to its destruction) while the navigator retained
a reference to the now deleted collision shape, leading to a crash.
