fix(discord): always emit import error if it's of type error

We've been limiting the amount of errors being emitted to clients
to reduce payload pressure and also due to the fact that we won't be
rendering more than 3 error items in the UI.

We want to let actual errors through (as opposed to warnings), even if
the limit was reached.
