Transaction does not revert if an error occurs

[ANDREYDEN]

Failing test:

test('does not add a document if a transaction fails', () async {
  final db = FakeFirebaseFirestore();

  try {
    await db.runTransaction((transaction) async {
      transaction.set(db.collection('test').doc(), {'name': 'Jane'});
      // the next line makes the transaction fail because reads should always come before writes
      await transaction.get(db.collection('test').doc('non-existent'));
    });
  } finally {
    final snapshot = await db.collection('test').get();
    expect(snapshot.docs, isEmpty);
  }
});
