add watchers to imports within vue files

Description

The watcher should rebuild vue files when the file's imports are updated. Without this, the rollup build doesn't rebuild when you update .ts and .scss/sass files that are in your build. This was fixed in vuejs/rollup-plugin-vue

Suggested solution

In plugin-vue/src/index.ts line 291, add this code snippet
if (query.src) {
this.addWatchFile(filename);
}
