fe25517295 adjusted the email_notifications codepath to use
`lxml.html.fragment_fromstring` method when parsing
`rendered_content`, but left the tests using a helper which called
`fromstring`.
Switching the tests to match the code as run reveals a bug -- using
`drop_tree` on all `message_inline_image` classes now _does_ remove
all of a top-level image-URL-only message. Previously, such messages
were "safe" from the block that calls `drop_tree` only by dint of
`drop_tree` being a silent no-op for the root element. When parsed
using `fragment_fromstring`, they are no longer the root, and as such
an empty message results.
Reorder relative_to_full_url to check for only one `message_inline_image`
within the top `<div>`, and only run the `drop_tree` path in the
alternate case. Tests must be adjusted for their output now including
one more layer of `<div>`.
