Confluence is sending an 'Unlike' notification

Steps to reproduce:

1. A user 'Like' a page and the page creator will received a notification:
   
2. The same user 'Unlike' the page and the page creator received the same/identical mail notification. This is misleading because the action is 'Unlike' instead of 'Like'.

Customer suggested that:

But it should rather say "<user_name> does not like your page anymore" or maybe "<user_name> changed the Like Status of your page", or something like this. Another solution would be not to send an email at all when someone "unlikes" a page.

Note: Tested on both English & Deutsch (Deutschland) language pack and this is affecting both languages.
