Let the WebDAV uploader's integration test find TestUtils

Merge branch 'test-utils'

Jenkins runs two uploader tests that ensure that the SSH and the WebDAV
uploaders work as expected. These tests are not run by default in
Maven's test phase because they take quite some time, and they require
a special server setup, passed in via Java properties, which is why only
Jenkins found the test failures, not this developer.

Thanks, Jeorjia Jenkins!
