copies: no longer change the sidedata flag

With the new sidedata storage that include data about all file changes, every
revision has one, so the sidedata flag is not longer a good way to spot
changeset with copy information. So we drop this check to simplify the code

We optimisation itself provided an interesting speedup, so we will likely
reintroduce something similar, with a dedicated flag, in the future.
