ActionValve logs warning on 404

Issue
When going to any url with the following in the request after the mount: '_hn:action|'
The ActionValve logs a warning: Illegal request for action URL found because there is no component for id 'r60_r1_r1_r1_r1' for matched sitemap item 'home'. Set 404 on response.

So if you go for instance to : http://www.mysite.nl/_hn:action| or http://www.mysite.nl/_hn:action|'r60_r1_r1_r1_r1|
The warning is logged and a 404 is set on the response. There should not be a warning in the log.

Solution:
Preferably this should be an info or debug log instead of a warning.
