ckaznocha 80d5a57b94 fix(matrix): commit the migrated account only after the session sweep
The account was written under the new pickle key before sessions were
re-pickled. The account is effectively the migration's commit marker —
once it reads under the current key, the fast path short-circuits every
later startup — so a sweep that errored or was interrupted left the
remaining legacy-key sessions stranded permanently with no retry.

Sweep first, commit the account last, and return False on sweep failure
so the migration is retried on the next start.

Also corrects the unreadable-row log: it claimed rows were being dropped
while no DELETE was ever issued. Such rows are left in place (already
unusable; deleting crypto material on a guess is not worth it) and the
message now says so.

Adds session-sweep coverage, which was previously absent: rows rewritten
under the current key, rows already current left alone, unreadable rows
left in place, and a failed sweep that leaves the account uncommitted.
The existing migration test now fakes the olm C-extension so the suite
no longer requires libolm.
