fix: Deal with different group orders

Fixes #6393

[rjsparks]

Unless I'm missing something this change cannot have fixed the bug. The change may be harmless, but if it actually does something, there's something more broken in the factories to address.

The bare calls to GroupFactory make names this way:
acronym = factory.Sequence(lambda n: 'acronym%d' %n)

So that call would have made acronym1, acronym2, and acronym3.

Hm. I wasn't actually able to reproduce the bug locally. Let me run the test for a few more hours to see if it kicks in.

Convinced by @rjsparks comment that there must be something else going on

We'll merge this. It might have been better to change what the sreq app does so that the output is deterministic, but the investment would be better made on replacing the sreq app.
