Fix query select and query projection

[dimasdanz]

The following projection does not work

DB::collection('items')->project(['tags' => ['$slice' => 1]])->get();

Because the new query driver is using option for projection.

And since selecting columns is now using projection too, this will also fix

$user = User::where('name', 'John Doe')->select('name')->first();

Added one more fix: Query using datetime instance
Because MongoDB\BSON\UTCDateTime expecting milliseconds and $datetime->getTimestamp returns value in seconds. So multiplying $datetime->getTimestamp value with 1000 will fix this
