EAP 7 access log has bad file name after rotation

Issue

• We've set up access logging like so with a . in our suffix:

<access-log pattern="%t %h %{i,X-Forwarded-For} %l %u &quot;%r&quot; %s %b %T" prefix="access" suffix=".log" directory="./" relative-to="custom.jboss.server.log.dir"/>

• The file is good at first (access.log), but after rotation it is accessYYYY-MM-DD..log. We'd expect access.YYYY-MM-DD.log.
