Adding a shared address book did nothing in one browser and worked in
another. The button was not broken; the refusal was invisible.
Subscribing is the one call in the app that writes to somebody else's
account, so it is the one a perfectly healthy server is entitled to say
no to -- and JMAP says no to a `/set` by answering successfully with the
object listed in `notUpdated`. Neither subscribe method looked. The
promise resolved, the code carried on, the re-read came back unchanged,
and the row stayed exactly where it was with nothing said.
Every other `/set` in this codebase reads `notUpdated` and raises. These
two were written without it, which is the whole defect: not a wrong
answer, an unread one.
Both now check it and say what the server said, which is the thing that
was missing -- whatever the underlying refusal turns out to be, it can be
read off the screen instead of guessed at from which browser was in
front of you.
