Don't convert newlines to <br> when input is HTML

[gRegorLove]

Specifically when converting HTML to Atom, the feed ends up with extra <br> around the existing <p>.

notes to myself:

• the <br>s get added here
• afaict we should keep converting newlines in p-content, but stop converting in e-content. background in Bridgy Publish to Facebook of "notes" should preserve whitespace formatting especially line-breaks bridgy#446 and https://indiewebcamp.com/note#Indieweb_whitespace_thinking
  • do mf2 parsers propagate these into content => text vs html, respectively?
• i tried adding html2text here, which worked, but broke lots of other stuff.

do mf2 parsers propagate these into content => text vs html, respectively?

e-content parses into value and html keys, but p-content wouldn't—just the plaintext value. It seems it would be safe to convert newlines in all instances except when the key is content => html
