Subject: [PATCH] Button missing getErrorsAsString() fixes #8084 Debug: Not
 calling undefined method anymore. If the form contained a submit button the
 call would fail and the debug of the form wasn't possible. Now it will work
 in all cases. This fixes #8084

Adding a test for the fix of getErrorAsString on Form.
Was throwing a fatal because of a method that did not exist on
the new element type button.
