Honour template path for plugins when creating unit tests.

Fixes GRAILS-9763. A hard-coded path in _GrailsCreateArtifacts meant that only
the src/templates/artifacts directory was searched in plugins when creating
unit tests. This broke Spock which had its templates in src/templates/testing.
The path now uses the `templatePath` variable.
