Cleanup various sonar issues in policy-common

Addressed the following issues:
- unused imports
- unused method parameters
- use assertEquals, assertSame instead of assertTrue
- provide the parametrized type for this generic

Also fixed some checkstyle issues:
- removed blank lines between "import" groups
