[Bug]: entrypoints of stats is not correct

[xusd320]

If an entry chunk has some deep level dependencies chunks, those deep level dependencies chunks are not collected.

For example:

entry.js
   -> splitted.js (dep of entry.js)
      -> splitted.splitted.js  (dep of splitted.js)

The stats output will be:

{
   entrypoints: {
      entry: {
        chunks: [
          // splitted.splitted.js is missed
          "splitted.js",
        ]
     }
   }
}
