webmention endpoint not discoverable from HTTP Link header

[jkrauss]

https://webmention.rocks/test/1
and
https://webmention.rocks/test/2
fail.
Error is: the header could not be discovered. The tests mention that the endpoint is exposed as a HTTP Link header.

Steps to reproduce:

from webmentiontools.send import WebmentionSend s = 'https://www.sumbee.net/try-webmention/' t = 'https://webmention.rocks/test/1' m = WebmentionSend(s, t) m.send()

fails with tests 1,2, suceeds with tests 3,4,5
