clone: warn when streaming was requested but couldn't be performed
This helps both users and the people who support them figure out why
a stream clone couldn't be performed.
In an upcoming patch we're going to add a way for servers to hard
abort on a full getbundle. In those cases servers might expect
clients to perform a stream clone, so it's important to communicate
why one couldn't be done.
