New timestamp config throwing error on init

[tommaitland]

• react-firestore version: 0.10.1
• firebase version: 5.5.8
• node version: 8
• npm (or yarn) version: 1.7 yarn

Relevant code or config

import firebase from '@firebase/app';
import '@firebase/firestore';
firebase.initializeApp(firebaseConfig);
<FirestoreProvider firebase={firebase} useTimestampsInSnapshots>

What you did:
It seems like the latest version of the package isn't initialising correctly due to how the timestamp settings are being set.

What happened:
Throwing the following error on load:

Firebase: firebase.firestore() takes either no argument or a Firebase App instance. (app/invalid-app-argument).

Suggested solution:
It seems to be caused by this line: https://github.com/green-arrow/react-firestore/blob/master/src/FirestoreProvider.js#L27

Untested, but I think it needs to be replaced with firebase.firestore().settings({ timestampsInSnapshots: this.props.useTimestampsInSnapshots}) before Line 26

@tommaitland - Thanks for reporting this! It should be fixed in v0.10.2
