Remove party cohort code.

We store/use the figures returned externally. Some of the tests are therefore now only testing that what is stored in the fixture is displayed, rather than any calculations involved. Should fix #1742. Is on top of other PRs.

This looks good - if you're happy with my amends:

• added autocommit settings when loading alignment information to speed that up.
• readded vote/division populator for dev setup from json.

Feels like I have to recombine/refactor those two scripts, given how much they do overlap :)

I've recombined these with a switch in a fixup commit - if that's good I can squish before merging.

One query, looks fine otherwise. More generally, though, just to check I understand - what's the reason to use this over the xml2db.pl import of divisions? Do you want to get votes in separately?

[ajparsons]

Sure - basically it's a speed of creating a working environment from scratch so the codespace prebuild takes an hour rather than a day.

For debates, I don't mind having a subsection (loading just one month), but for double checking the voting records I want to have all relevant votes, and to do that means downloading and importing thousands of days of debates and votes, which significantly increases the build time.

Ideally, I'd just do that - but given the dev setup was working with the json import, and twfy-votes has continuity with the old format - may as well keep it.

I can't approve my own PR, but happy with it!
