initremote --sameas fully working

And using sameas remotes is working.

Moved annex-config-uuid setting out of Remote.Helper.Special.
EnableRemote will also have to set it.

 Implementation notes:
 
-initremote --sameas ends up with the annex-uuid and the annex-config-uuid

 Need to get enableremote working for sameas.
 
 Deal with the per-remote state issue.
