Lock Status Test fails on Nuxeo JS Client

The Client JS here fails. Caused by a test failure on document.spec.js

Lock Status
lock
should throw an error when locking a document already locked:
Error: done() invoked with non-Error: Must not resolved when locking a document already locked

This test failed because we assume that a locked document cannot be re-locked by the same user. According to see now a locked document should be re-locked by the lock owner. However this locked document cannot be locked by an other user then the lock owner.
