Delete EvaluatedPropertyReferenceType from Common.xsd to align with Operations Test Model

[CharlieG021163]

Work in Progress
ERDi, MESA: Related to #21, #101
Background

1. In the updated 950002 Operations Test Model, the relationship source role name is not a required schema element for the "Corresponds to" unidirectional relationship from the Evaluated Property object (source) (under the Test Specification object) to the xxxProperty object (target, Testable Object Property).
2. In B2MML, the EvaluatedPropertyReference element is not necessary and creates a circular reference since the Testable Object Property has a composite relationship to the Testable object which has the "specifies" relationship to associated TestSpecification element. The TestSpecifictionID identifies the defined the EvaluateProperty(s) by it composite relationship.
   There is No reference attribute required since the Testable object has a TestSpecification element/attribute which provides the Evaluated Property which references the Testable Property element/attribute.

This requires discussion, and perhaps a description if needs to be submitted to MESA
