rebase: don't forward "source" argument to rebase (issue4633)
`hg pull` takes an optional "source" argument to define the path/url to
pull from. Under some circumstances, this option could get proxied to
rebase and interpretted as the --source argument to rebase, leading to
unexpected behavior.
In my local environment, "source" always appears in "opts" in
pullrebase. However, when attempting to write a test, I couldn't reproduce
this. Instead, the source is being captured as a positional argument in
"args." I suspect an interaction between **kwargs and an extension is to
blame for the differences in behavior. This is why no test has been
written.
I have tested behavior locally and the patch has the intended
side-effect of making `hg pull --rebase` work again.
