HRSPLT-172 Clean up traces of confirmations code

#13 carelessly missed some traces of the no-longer-needed Confirmations code, such that Spring context won't init!  My bad. :anguished: 

This:

 * Removes the Schema Definition (XSD) that defined Benefit Confirmations (`benefit-confirmations.xsd`).
 * Removes the entry in `bindings.xjb` referencing that removed XSD.
 * Removes the package from `JAXBContext` bind parse path in both the real application context and the test application context.
 * Removes the `cypress-override.properties` entries that set JavaBean properties on the no-longer-existing `restBenefitConfirmationDao`.

Also:

 * Trivial: Style : Adds a newline to the end of a couple Spring application context XML files.
