evolve: delete dead calculation of number of troubled revisions
The "count" variable is recalculated in the regular (no --continue)
code path and it isn't used anywhere else (it used to be set to 1 in
the --continue code path, but that now has its own progress counting).

evolve: drop nested locks and transactions
All callers of _solveone() now take the locks and start the
transactions, so there's no need to do that anymore.

next: start transaction before calling _solveone()
All other callers do this, and I'm about to make _solveone() not
create a transaction.
