Describe the problem you have without this PR

The problem is described and discussed here: #6988

This PR makes the DB8 error handling easier by introducing the closeDuplicates flag which will close all duplicate instances before initializing a new instance:

const db1 = await createRxDatabase({ name, storage });
const db2 = await createRxDatabase({ name, storage, closeDuplicates: true }); // would throw DB8 error without `closeDuplicates: true`

console.log(db1.closed); // true
console.log(db2.closed); // false
