Common code to get the session hints. Will get guesses if there were
no completions for the query.

@param {string} query - user text to search hints with
@param {{line:number, ch:number}} cursor - the location where the hints
were created.
@param {{property: boolean,
showFunctionType:boolean,
context: string,
functionCallPos: {line:number, ch:number}}} type -
type information about the hints
@param {Object} token - CodeMirror token
@param {jQuery.Deferred=} $deferredHints - existing Deferred we need to
resolve (optional). If not supplied a new Deferred will be created if
needed.
@return {Object + jQuery.Deferred} - hint response (immediate or
deferred) as defined by the CodeHintManager API
