Default review objectives used inconsistently from branch reviews/smart commits reviews

There are two cases in which reviews objective are set automatically:

Using Smart Commits

The commit message of the commits involved are added as a review objective. This ignores also what's set as default review objectives in the project, so for now I think there's no workaround in this case.

Using Branch Review

Currently, when a branch is chosen for review, if no default review objectives are set for the project, the commit messages of the commits in the branch are added as objectives.

The suggestion is to allow the user to choose among:

• Having the commit messages added as objectives.
• Not having any objectives at all.
• Possible 3rd option: add the default objectives as objectives of the review.

In case the user doesn't want any objectives set at all the workaround is to set an empty space character as default review objectives in this project.
