Does not autocomplete iron

[Emilgardis]

Currently racer fails to autocomplete iron, no clue why.
Gist for all related files.
#499 may be related.

@Emilgardis It does. It just can't parse imports when you write use module::something::*; such as use iron::prelude::*;. So, if you will import symbols manually like use iron::Iron;, it will AC fine.

UPD: Sorry, just noticed that it imports other symbols from iron::prelude. Hmm...

This looks to be a duplicate of #499, unless I'm missing something. Closing this to focus the discussion there.
