Merge Fix for GLASSFISH-21007

Ok it would be useful to set the request to false after the upgrade has been called rather than doing the above. This pull request was more to give you an idea as to how it could be possibly handled. There are two valve calls when the access log is enabled here: one associated with StandardHostValve which processses the web socket request as expected and the other associated with PEAccessLogValve. Writes to the access log is not affected by the change above.

The valve com.sun.enterprise.web.PEAccessLogValve causes the problem but I added a check also for AccessLogValve also. This valve is only active as expected if the access log is enabled.
