Fixed - actually there were two places which needed fixing, I also somewhat simplified the
logic Thank you!

> Inside the Fetcher class if a redirect URL is filtered, for example jessionid pages are
filtered with the default URL filter, then a NullPointerException is thrown when Fetcher trys
to print out that the url was skipped for being an identical url.  It is not an identical
URL but a filtered url.  So what we really need is two different checks.  One for null url
and one for identical url.  I have included a patch that handles this.
