tighter recps guards

[mixmix]

the create() method uses this to pick the recps for encryption

const recps = fullOpts.recps || fullOpts.content.recps

https://github.com/ssbc/ssb-db2/blob/master/core.js#L663

The docs don't mention which wins if both set. Also this code allows both the be set, and for a message to be encrypted to different people than it advertises to.

I'm not sure if this is a footgun... my gut tells me you should never have them be different

The intention was to gradually move away from content.recps and prefer recps because content.recps ends up getting deleted from content actually I'm wrong, shit, I thought that was how it worked. I guess we need to prefer content.recps because that's how other peers get to know who are the participants in a box1 private chat. :cringe:

So yes, somewhat footguny.
