Agent.stop doesn't close store

[mixmix]

Is this a regression?

No

Description

We've written some persistence test for our application, but they fail because agent.stop does not stop all aspects of the agent. Namely the Pluto.Store continues to run, so that when you try and restart a new instance of the agent you get RxDB freaking out (correctly) about another instance of your db already running

Please provide the exception or error you saw

RxError (DB8): RxError (DB8):
  RxDB Error-Code DB8.
  Error messages are not included in RxDB core to reduce build size.
  - To find out what this error means, either use the dev-mode-plugin https://rxdb.info/dev-mode.html
  - or search for the error code here: https://github.com/pubkey/rxdb/search?q=DB8

Please provide the environment you discovered this bug in

SDK `5.1.1` with `@pluto-encrypted/inmemory`

Anything else?

Here's that Errror message looked up to save you the hassle : https://github.com/pubkey/rxdb/blob/c50e7c96f8f6bbaecefbb34673916f720c037edb/src/plugins/dev-mode/error-messages.ts#L68

Propose

inside agent.stop() add await this.store.stop() or whatever

Hi @mixmix,
I've got a PR up for this (#309)
While I've added unit tests and manually tested against our demos, I would really appreciate if you could try the branch with your persistence tests and let me know the outcome.
