close does not close dependent dbs fully #7331
Description
Issue
Closing a database does not seem to close the dependent dbs / views / indices.
So one can not repair / rebuild the indices without a restart
Info
- Environment: node
- Platform: macos / Win
- Adapter: leveldb
- Server: Pouch db
Reproduce
Flow:
- Create a db
- Create an index / view
- Close the database
- delete the view directories
- reopen the database
- try to use the index

PouchDB.plugin(require('pouchdb-find'))
const fs = require('fs')
const expect = require('chai').expect
const path = require('path')
const util = require('util')
