Salvo 'LtWorf' Tomaselli a8c1b2a463 Revert copy on write optimization ...

In case of multiple renames, all of the resulting relations will point
to the same data, so writing on one and marking its only known copy
as writable would be incorrect.

For this to work, all the references should be kown to all the other
instances.

It is probably not worth to implement it.

Implemented test for the update
