rebase: fix pull --rev options clashing with --rebase (issue3619)

Rebase also have a plain `--rev` option used to select the rebase set (as
`--base` or `--source` would). But the content of the --rev option was intended
for the remote repo and is irrelevant for the local rebase operation. We expect
`hg pull --rebase` to stick with the default behavior here:

    hg rebase --base . --dest tip(branch(.))

The `rev` option is dropped from the option passed to rebase.
