Resolve legacy dependency pouchdb-all-dbs

[openscript]

Case

It is an improvement. Nothing is broken.

Issue

When I install the dependencies (one of them is rxdb) I get the following warning:

warning Pattern ["esprima-fb@~3001.0001.0000-dev-harmony-fb"] is trying to unpack in the same destination "/home/node/.cache/yarn/v6/npm-esprima-fb-3001.1.0-dev-harmony-fb-b77d37abcd38ea0b77426bb8bc2922ce6b426411-integrity/node_modules/esprima-fb" as pattern ["esprima-fb@~3001.1.0-dev-harmony-fb"]. This could result in non-deterministic behavior, skipping.

Info

• Environment: node.js 14.15.1 with yarn
• Adapter: doesn't matter
• Stack: doesn't matter

Code

I've investigated this for a bit.

$ yarn why esprima-fb

pouchdb-all-dbs wasn't updated for a few years. It is only used once in rxdb:

rxdb/src/plugins/server.ts

Lines 36 to 39 in 8e02730

	// we have to clean up after tests so there is no stupid logging
	// @link https://github.com/pouchdb/pouchdb-server/issues/226
	const PouchdbAllDbs = require('pouchdb-all-dbs');
	PouchdbAllDbs(PouchDB);

Honestly I don't 100% understand why this is needed, but I would happy to help to replace this dependency.

As far as I remember, I needed that to fix some problems when using the same db instance multiple times. pouchdb/pouchdb-server#226
If you can, please remove the dependency. As long as the CI stays green of course.
