Wrong error message when editing own glossary entry after timeout

1. Create a glossary activity
   • Ensure the "Always allow editing" setting is set to No
   • Leave other settings as defaults
2. Login as a student
3. Access the glossary.
4. Add a new entry with a Concept and Definition
5. Click the 'Save changes' button.
6. Stay on the Glossary view page (which should show the editing icon) and wait 30min (or less if you can reduce $CFG->maxeditingtime)
7. Try editing the entry.

Expected result: The user should be shown a timeout error.

Actual result: An error about the user not being able to edit other's entries is shown.

You cannot edit other people's entries.
