In watch mode when the code imports CommonJS from ESM, depending on the setup, it can happen that the ES to Commonjs proxy module is re-evaluated. If that happens, its meta information is lost, leading to a weird crash.

Description
I stumbled upon a case where in watch mode when changing a file, the CommonJS plugin would show a weird error. What happened is that a proxy module that was generated for a CommonJS from ESM import was being re-evaluated in its importer's
shouldTransformCachedModulehook. Due to a small bug, the meta information of the proxy was lost, leading to a crash. This fixes it by supplying this meta information via loading the full resolved id object (that contains the meta information) instead of just using the id.
