Issue Summary

DVCS connector incorrectly maps the authors of merge requests. The bug doesn't affect commits' authors and reviewers.

Steps to Reproduce

1. Create two GitLab users with the same Full Name.
2. Create a merge request with user A.
3. Create another merge request with user B.
4. Synchronize merge requests.

Expected Results

Both synchronized merge requests show correct authors in the development panel.

Actual Results

Synchronized merge requests show incorrect authors in the development panel.

Workaround

Do not use the same full names for GitLab users.
To fix the incorrectly mapped names, replace the full names stored in the column "Author" in the table "AO_E8B6CC_PULL_REQUEST" with usernames.
