[tree] Copy adresses instead of resetting all

If we just reset the addresses of the clone, the address are now valid but the current tree and the clone are still separated. [As a side note calling ResetBranchAddresses actually does too much because it also reset branch address that are unrelated to the original, for example branches that have been added to the clone).
