GH-1920 --A-- Fix duplicate js imports, but not xhr sync warning

[brianzelip]

This PR is the first of 3 proposed solutions to #1920 (see there for info about all 3 PRs).

This only fixes the duplicated imports by moving the include_tag up the DOM and out of the template loop.

This does not fix the synchronous xhr warning.
