Previously, in the embark cli dashboard/console, if you were to type `Foo.` and
hit tab for autocomplete then (assuming you hadn't defined `Foo`) there would
be unhandled errors and the console could even become unusable.
Refactor `packages/core/console` and related code so that nothing happens when
you attempt to autocomplete a bad reference (the same behavior as Node's own
REPL).
