split: close transaction in the unlikely event of a conflict while rebasing

`hg split` *should* never result in conflicts, but in case there are
bugs, we should at least commit the transaction so they can continue
the rebase. One of our users ran into the regression fixed by
D10120. They fixed the conflict and the tried to continue the rebase,
but it failed with "abort: cannot continue inconsistent rebase"
because the rebase state referred to commits written in a transaction
that was never committed.

Side note: `hg split` should probably turn off copy tracing to reduce
the impact of such bugs, and to speed it up as well. Copies made in
the rebased commits should still be respected because `hg rebase`
calls `copies.graftcopies()`.

#require sqlite

Tests for wire protocol version 2 exchange.
Tests in this file should be folded into existing tests once protocol
v2 has enough features that it can be enabled via #testcase in existing
tests.
