[Issues] Memory leak in ReduceTask recipe

[Ewout M. Helmich]

I have added various lines like "self.bias.image = None" in the 
ReducedScienceFrame class. Presumably that should fix (or at least 
drastically reduce) the problem. If you could check to see if the 
changes have helped, that would be nice.

Regards,
Ewout
