[PATCH] Fix `_description -J`

[dana <dana@xxxxxxx>]

I noticed that workers/44274 introduced a bug related to `_description -J`.
When invoked this way, the function now adds -J to expl twice, yielding
something like...

  -J -J foo -X 'completing foo:'

... which breaks completion.

Can we simply do this? My brain is too muddy right now to understand the full
implications, but it seems like it should work...?

(Can't remember why i actually wanted to use `_description -J`; just found it
in one of my functions)
