"qisrc push --no-review" tries to set reviewers

[plemagourou]

Even if qisrc push was launch with the option --no-review, qisrc tries to add reviewers and a failure warning is printed. The push command is well executed though.

Here are a few lines that show the problem:

qisrc push --no-review
Fetching gerrit
Total 0 (delta 0), reused 0 (delta 0)
remote: Processing changes: closed: 1, refs: 1, done
[...]
Adding reviewers... (user1, user2)
[...]
[WARN ]: Couldn't set reviewers

Return code is 1
