.vue Components with empty lang="scss" style tag crash gulp on build

[VanceCole]

Should reproduce with following component

<template>
  <div class="example">
    test
  </div>
</template>

<script>
export default {
  data() {
    
  }
}
</script>

<style lang="scss">
</style>

Yeah, gulp also fails if the file is empty, and the scoped portion doesn't work, and if we add a style section, then we can't use a beforeCreate hook anymore in the vue component.
I blame it all on the vue component module for gulp, which is old, outdated and sucks (but just does the job), and is one of the reasons I want to eventually investigate the use of webpack. Gulp does the job to get us started, but it has some quirks that become more apparent as we require more complex things.
