Issue #3458854: Fix url in getRelatedEntityUrl if entity doesn't have canonical link

[Kovalskiy266]

Problem

Sometimes the entity related to the activity does not have a canonical URL, which causes a fatal error when viewing the activity. This error occurs because there is no check to see if the entity has a canonical LinkTemplate

Solution

Add condition with check if the entity has canonical linkTemplate
