[Eloquent] Bug with eager loading relationships and isset()

Calling update() on an eloquent model has no way of overriding
the timestamp that should be set if $timestamps is set on the
model. This changes that so it uses the timestamp() function
which is an easy way to over ride the type of timestamps used.
