Jira macro displays the public name of users instead of their full name for people from their organization

Issue Summary

Scenario:
The user has configured under profile and visibility that only people in their organization can see their Full Name. In that case, anyone who's outside their organization will see their Public Name.

In Jira, users from the same organization will see the users' names as their full names. However, when adding the Jira macro to a Confluence page, the public name of that user will be shown.

Steps to Reproduce

1. Create a test user and add them to your organization.
2. Under profile and visibility, make their Full Name restricted to people from their organization.
3. Give a Public Name different from the Full Name.
4. Give the test user access to Jira and assign them to an issue.
5. On Confluence, create a page.
6. Add the Jira macro and make it display the issue from Jira.

Expected Results

We should be able to see the Full name of the user on the Confluence page as well.

Actual Results

In Jira, we see the user's Full Name, in Confluence we see their Public Name.
The below exception is thrown in the xxxxxxx.log file:

Workaround

If possible, ask the users' to have the name Public Name and Full Name.
