Fixed a duplicate comma bug when using a trailing comma:
<script lang="ts">
const react = sveltify({ div: "div", });
</script>
<react.div>
<react.span>Text</react.span>
</react.div>The preprocessor would detect the missing 'span' and add it to the sveltify object but generate:
sveltify({ div: "div", , span: "span"});Resulting in a Property assignment expected error
