Fix mp-listall Studio releases listing

In Studio project named "StudioProject"

• I create two releases named 0.0.0 and 0.0.1

In NXP I launch the following:
user/password = solen/test

./nuxeoctl mp-listall | grep "Studio"
studio      remote	StudioProject (id: StudioProject-0.0.0-SNAPSHOT)

=> My releases are not listed
