AnnotationReference.toAnnotationSpec() generates faulty code when argument is varargs

[matejdro]

When input annotation has vararg parameters (for example, @Suppress annotation), AnnotationReference.toAnnotationSpec() will generate new annotation with named parameters, which is not valid (vararg parameters should not be named).

For example, @Suppres("unused") will be converted to @Suppress(names = "unused").

This will cause the compilation of the generated kotlin file to fail with the Assigning single elements to varargs in named form is forbidden error.
