feed: dirty fix to show replies

now that nonce tag is always the first element in the tags list,
a bug surfaced that replies from nostrweb did not render anymore.

reason was that the code expected the first tag to be an e tag and
took its reply-id. this commit is a quick fix that takes the first
reply-id fromt the first e tag.

the proper way is a bit more complicated as nip-10 defines a
preferred and deprecated way.

this is a quick and dirty fix so that replies work with nip-13 pow
events, but nip-10 event tags should be properly supported but in
a later commit.
