Some changes to test handling.

- Add grails-core jar to testRuntime classpath and make test tasks dependent on the jar.
- Remove 'target' dir from testRuntime classpath (it never belonged there).
- Changed order in which build scripts are applied so that the jar task is available to the test tasks.
- Refactoring: Move testRuntime declaration to unit-test.gradle.
