fix(search): an edited message shows once, with its latest text (#288)

Server search also returns the m.replace events, so one message edited
twice came back as three rows. Fold edits into their message: one row
at the best-ranked position, showing the latest m.new_content and
pointing at the original event so Open jumps to the real message.

Fixes #288
