QtContacts: Add missing entries to schema definition
QtContacts: Add missing entries to schema definition

QContactOrganization::FieldAssistantName and
QContactOrganization::FieldRole are missing from the schema
definitions although those fields exist since QtMobility 1.0.

One side effect of this is that
QContactManager::compatibleContact() will drop these fields.

Upstream bug: QTMOBILITY-1592.
