Merge 'Fix overwrite cell with size less than cell size' from Pere Diaz Bou
...
We cannot simply paste a new payload into a cell with a payload with
less size because we need to track fragmentation + free blocks. Let's
keep it simple by only overwriting if size is the same.
Btw I feel like update is not re-entrant.

overwrite when payload is equal size as current cell only
...
Prevoiusly we would overwrite even though size less than cell size. This
was wrong because it didn't update any fragment size or free blocks it
could. To be safe let's just overwrite only if local size is the same
amount.
