* style & formatting. fixes#1859
* prepare `choices` in `updateSelectizeInput()` as per discussion in #1861
* remove duplicated block in selectizeJSON, simply `lab` assignement logic
* Fix#1824: HEAD request on static files causes app to stop
The problem was that for HEAD requests specifically, we implement
an explicit Content-Length header (normally we let httpuv figure
out the Content-Length based on the content, but for HEAD we don't
return any content but still want to include the Content-Length).
The Content-Length header was only implemented correctly for string
values, not for raw vectors or file-by-path. This change implements
the value correctly for all currently valid httpuv content.

* change code place
* Code review feedback
* onStop: use session argument instead of scope
