rebase --interactive: Compute upstream SHA1 before switching branches
If the upstream argument to rebase (the first argument) was relative to
HEAD and the name of the branch to rebase (the second argument) was given,
the upstream would have been interpreted relative to the second argument.
In particular, this command
git rebase -i HEAD topic
would always finish with "Nothing to do". (a1bf91e
fixed the same issue
for non-interactive rebase.)
