Paste feature does not work if JIRA links are pasted by regular (non-admin) users

Steps to reproduce

1. Login as Admin
2. Install JIRA CKEditor Integration 
3. Go to Administer Wiki > Editing > WYSIWYG Editor and paste the following in the Advanced Configuration section: config.extraPlugins = 'xwiki-jira-paste';
4. Go to Administer Wiki > Other > JIRA and add a JIRA instance. For ex:

• Id: JIRA1 (or any other ID)
• JIRA URL: https://jira.xwiki.org

1. Click 'Save'
2. Login with a regular user
3. Edit a page with CKEditor and insert a JIRA link, e.g. https://jira.xwiki.org/issues/?jql=issuekey%20in%20(XWIKI-21300%2C%20XWIKI-21310) or https://jira.xwiki.org/browse/XWIKI-23911

Expected results

The pasted JIRA link resulted in inserting automatically the JIRA macro containing the respective tickets.

Actual results

The JIRA link is pasted as a regular link.

The issue does not reproduce if the JIRA links are pasted by an Admin.
