Remove call to non-existing AphrontTypeaheadTemplateView::renderToken()
Summary:
`AphrontTypeaheadTemplateView::renderToken()` is an undefined method,
and its result is stored in an orphan variable, and no child class
extends `AphrontTypeaheadTemplateView` defining a `renderToken()`.
Thus remove its call from `AphrontTypeaheadTemplateView::render()`.
Test Plan: Read/grep the code in this class.
