Nils being inserted into updates that don't have them.

[RealNobody]

I'm trying to use the gem, but I can't because it is inserting NIL values where I don't want them.

The basic problem is this:

data = [ { id: '1', Field_1__c: nil}, { id: '2', Field_2__c: nil] } ]

bulk_api.update(:contact, data, true, true)

What I expect is for record 1 to have Field_1__c set to nil, and record 2 to have Field_2__c set to nil. What I get is both records having both fields blanked out.
