fix: fix rendered code when user defined props are not passed

[godnondsilva]

Problem Description

If the user does not pass any custom props, then the generated code will have an extra comma (,)
Example:

Button.mist.css

@scope (.button) {
  button:scope {
    /* Default style */
    font-size: 1rem;
    border-radius: 0.25rem;
  }
}

Button.mist.tsx

export function Button ({ className, , ...props }: Props) {
