Remove classes from system templates t*.html.twig

Postponing this until we decide how we are moving forward. Keep an eye on #2348543: [meta] Consensus Banana Phase 2, transition templates to the starterkit theme for updates. Thanks.

Un-postponing. The templates have been copied to Classy, so all we need to do is remove classes from the original templates.

we need visual confirmation on resizable textareas still works without classes, else selector classes must be prefixed with .js-

function testThemeTableWithEmptyMessage() in tableTest.php needs to test on classy not on stark

fixed the test

screenshots added of resize

Removed text-area class that was set from the module : housecleaning

Reuploaded patch from #16 - im an idiot so it was named as beeing F* templates, so lets try with the right letter

One issue: .form-textarea class is still added to the textarea, when using stark.
Looks like it gets the name from form.inc

function template_preprocess_textarea(&$variables) {
  $element = $variables['element'];
  Element::setAttributes($element, array('id', 'name', 'rows', 'cols', 'placeholder'));
  Element\RenderElement::setAttributes($element, array('form-textarea'));
  $variables['wrapper_attributes'] = new Attribute();

Dunno why this is added but its there.
We could make a cowboy solution and use {{ attributes.removeClass('form-textarea') }} on the core template, but thats to ugly even for sloppy themers ;)

Anybody got a clue on why & where this comes from or should be make it into a followup issue & get the templates cleaned up now ?

lets try thins again

Good job, @mortendk! Yeah!
