Fluid: Fix for Python pointer update (flickering in smoke/fire issue)

In f2b04302cdec the pointer update was refactored. It was sufficient to update pointers just in replay mode at the end of a step since the 'ensure()' functions from manta_fluid_API.cpp had their own pointer update call. These were removed in 51f4bee5a5d7, however, and so in order to still have some sort of update, the given update call needs to be available to all cache types.
