Story

As a Maintainer
I want an effective test method for the Region(Collection\<Voter>) constructor
so that the constructor is tested and test coverage of the Region class is more complete.

Acceptance Criteria

• At least one test method exists in RegionTest for the Region(Collection\<Voter>) constructor.
• All executable lines of the Region(Collection\<Voter>) constructor are exercised during automated unit testing.

Coverage cannot be checked because the Junit 5 Jupiter tests are not compatible with the current JaCoCo configuration.
