Jerko Steiner 0cb432cb82 Add TypeScript autoimport support for deoplete (#2779)
* Add autoimport support for deoplete

* Fix test_deoplete_source.py

* Use callback instead of is_async for deoplete

Shuogo, the author of Deoplete, does not recommend using the `is_async`
option:

> I think is_async is not recommended. It is not so useful and broken.
> You should use callback system instead.

Incidentally, the same thread mentiones an issue started by w0rp:
https://github.com/Shougo/deoplete.nvim/issues/976

The deoplete docs also say is_async is deprecated:

> is_async        (Bool)
>     If the gather is asynchronous, the source must set
>     it to "True". A typical strategy for an asynchronous
>     gather_candidates method to use this flag is to
>     set is_async flag to True while results are being
>     produced in the background (optionally, returning them
>     as they become ready). Once background processing
>     has completed, is_async flag should be set to False
>     indicating that this is the last portion of the
>     candidates.
>
>     Note: The feature is deprecated and not recommended.
>     You should use callback system by
>     |deoplete#auto_complete()| instead.
