JQL filters display accountID

Summary

Currently, using JQL in Issue Navigator will change "Reporter" or "Assignee" name to AAID when the name is selected from the drop-down list. It would be good to have better JQL UI experience in Issue Navigator.

Steps to Reproduce

1. Go to Issue Navigator and switch to JQL
2. Type "reporter = " or "assignee = "
3. List of users will be listed in the drop-down list
4. Select one of the users

Expected Results

JQL created would be:

reporter = <name>

Actual Results

JQL created:

reporter = <AAID>

Workaround

Click on "Switch to Basic", then click back on "Switch to JQL", the AAID will be changed to name.

Original description

When you are creating a search, if you type the initial letter from a user, you will see a pop-up suggesting you some names and if you click over any new user which has the accountID the JQL will use the accountID instead of the user name or display name.
This is expected due to the GDPR. But, this is not user friendly because if we save the filter, the accountID will be there and other people will not know who is the user belonging the accountID.

We would like to improve the behavior on the filters in order to at least the filters show user's display names instead of accountID.
