Disable autosuggest

Summary:
There is currently a regression bug with autosuggest that will not get fixed in the next few weeks,
so we've decided to disable it entirely.
I saw a few different places I could disable it -- I could also do it in live-editor.js,
tooltipEngine.setEnabledStatus. That code confuses me since setEnabledStatus actually only
sets the enabled status of autosuggest, from what I can tell, but it might be the better place
to disable it. What do you think?

Test Plan:
- Create new program at /cs/new/pjs. Type ba, don't see autosuggest.
 Type rect, see documentation tooltip popup. Complete rect command, be able to use number scrubbers.
 Type fill, use color picker successfully.
