Query options passed to .rest() are only parsed when 'queryCols' exists

[gitbrent]

The .rest() method is ignoring options (not including them in REST queries) when queryCols is not included:

CODE:

sprLib.rest({ url:'/sites/dev/_api/web/lists', queryFilter:'ID eq 99' })

RequestURL:
/sites/dev/_api/web/lists?_=1507783353329

CODE:

sprLib.rest({ url:'/sites/dev/_api/web/lists', queryCols:'ID', queryFilter:'ID eq 99' })

RequestURL:
/sites/dev/_api/web/lists?$select=ID&$top=1000&$filter=ID%20eq%2099&_=1507783353336

Fixed. Lots of new QUnit tests added for sprLib.rest() param parsing now.
