Fix empty JaCoCo aggregate report by including test modules

The aggregate coverage report was empty because JaCoCo's report-aggregate
goal requires dependencies on the modules containing both the code to be
measured and the tests generating the coverage.

This update:
- Includes all relevant test modules (`org.moreunit.core.test`,
  `org.moreunit.mock.test`, `org.moreunit.swtbot.test`,
  `org.moreunit.test`, `org.moreunit.mock.it`) as dependencies in the
  `org.moreunit.report` module.
- Fixes incorrect groupIds for several dependencies in the reporting
  module.

This ensures that JaCoCo can correctly associate the execution data
with the source code and generate a comprehensive report.
