Sites own domain appears in referrers after upgrading to v2.16.1 #3256
Description
Describe the Bug
After upgrading to 2.16.1, the domain of the site tracked started appearing in the list of referrers, as if it was a traffic source for itself.
I am fairly confident it was not there in 2.15.1 and don't recall seeing it there in 2.16.0 either, although I only ran that version shortly before 2.16.1 dropped.

Same here, for some users we have our own website as referrers. This is the case since the installation of Umami about a year ago.
We are using the hosted version.

It appears this issue is still present in Umami v3

Taking a look at the code the app excludes the referrer if hostname = referrer. I guess there are conditions where this exclusion would not apply.

Thanks for looking into this. Shouldn't the check also exclude the domain with www. prefix?
Debugging my website_event records I see hits with both domain.com and www.domain.com as hostname, while referrer_domain is always domain.com.
remove www. prefix from hostname during comparison. Closes #3256
