Push does not take MongoDate

[alwaysanirudh]

Hi,

I have been facing this issue after the update. I'm Trying to push an array to mongo collection described as follows:

$activityItem = [ 'text' => 'blah blah', 'date' => new MongoDate() ];
DB::collection('customers')->where('name', 'XYZ')->push('activity', $activityItem);

But I get a error when I run it.

Object of class MongoDate could not be converted.

I tried to do a raw query and it did work fine.
I think there is a problem when we try to do a push and Base model tries to convert the data.

Seems to be ok in the unit tests, can you check commit b31f54a?
