Tidy dependencies and scopes in POMs

Tidy dependencies and scopes in POMs

There were some duplicate dependencies in the POMs that were causing warnings.
These have been removed. In cases where the revision of the duplicate
dependencies were different,the latest revision was used.

The scope of the "junit" dependency was "provided" in some POMs. These have been
corrected with the scope of "test" being used for junit dependencies.
