Test Refactoring: consolidating tests under core/filters/services direct...

Jenkins has 3 jobs that are running all non-categorized tests in the following 3 directories: features/core, features/filters, features/services.

Tests were added to new subdirs under features, but these tests are not being run in Jenkins unless they had a @Category(Slow) tag associated with them.

Refactored and moved test subdirs around to follow the core/filters/services pattern.  Ran the tests I moved locally, and all are passing.
