Bad urls cached to early

New issue for:

I have found yet another bug when creating issue #128. When I tried to give you an url to Bridgy (which does not have its webmention target defined) like homepage or about page it got catched as bad url and later on all syndication urls to bridgy were ignored.

So I needed to underscore all urls dot “.” to make wrong domain and not ignore syndication urls.

Maybe cache should be written only after sending all webmentions in batch? Not during send?

maybe this is the only one url which causes the issue - so that will be easier maybe to make it whitelisted in code?
