Labels aren't clickable in "User has added/removed label X" messages

[Wuzzy2]

Description

If someone adds or removes labels, the issue history will show messages like "User has added label X 4 hours ago". However, the labels aren't clickable links, they are just text.

I suggest to turn these into clickable links.
