Consider sortBy header when performing findOneByQuery operation
There is a often a requirement to fetch the min/max record from Mongo based
on a particular field. Typically the operation is performed using syntax
similar to:
db.collection.find().sort({_id: -1}).limit(1)
or
db.collection.findOne({$query:{},$orderby:{_id:-1}})
As implemented the findOneByQuery operation currently ignores the sortBy
header. This trivial patch passes sortBy to the sort parameter of findOne(), if
set.
Helpfully, if the projection parameter is null findOne() returns all
fields, so the state of fieldFilter is not checked before passing when the
sortBy header has been set.
