No Jira link is made when GitLab user has no permission for commenting

Summary

I wanted to stop GitLab leaving annoying comments in Jira:

[User Name|http://gitlab_host.tld/user.name] mentioned this issue in [a merge request of Group/Project|http://gitlab_host.tld/Group/Project/merge_requests/MR_ID]:
'MR Title'

Since I want to keep external links to easily navigate from Jira to GitLab I just revoked permissions for adding comments on Jira side for GitLab user, since I wasn't able to see option to disable these annoying comments in GL. Unfortunately the result is not what I expected - no links or comments are created.

Steps to reproduce

1. Configure Jira<>GL integration as stated in manual
2. Enable integration via keywords in MRs on GL side
3. Revoke comments add permission on Jira side for GL user
4. Create MR with issue key from Jira

Expected behavior

Link is created while comment is not.

Actual behavior

No link nor comment are created.

Possible fixes

I see two possible fixes:

• Hotfix: Creating link and comment should be separated and failure to create one should not affect other one.
• Proper fix: Add controls whatever comments or/and links should be created.
