Server-switch gets confused if a domain is a subset of another

[diox]

Steps to reproduce:

1. Create a bookmarklet with 2 domains, in this order: www.example.org and stagewww.example.org. The first one needs to be contained in the second one.
2. Go to second domain (stagewww)
3. Bookmarklet thinks you are on the first one because it matches. It shows the wrong domain with an incorrect link (it will show a stagewww link, since it thinks you are on the other one, but in addition the href will point to stagestagewww.example.org because of the replacing it does)

It should not happen :-) A workaround is to simply different subdomains when you can (like wwwstage instead of stagewww).
