Nick Craig-Wood 75fc3fe389 fs: fix FixRangeOption so it doesn't add HTTPOptions in place of bad Ranges
Before this fix, FixRangeOption would substitute RangeOptions it
wanted to get rid of with with empty HTTPOption. This caused a problem
now that backends interpret HTTPOptions.

This fix subsitutes those with NullOptions which aren't interpreted as
HTTPOptions. This patch also improves the unit tests.
