org-colview: Fix `org-columns-view' and `org-columns-edit-value'

* lisp/org-colview.el (org-columns-new): Change signature to allow both
  editing and column creation non-interactively.
(org-columns-edit-attributes): Use new signature.
* testing/lisp/test-org-colview.el (test-org-colview/columns-new):
  Update tests.
