Secondary resolveId calls on virtual modules

[epfremmer]

Describe the bug

The resolveId method on plugins which return a virtual module is called a second time with the previously resolved module id. It seems odd this would happen which made me question if this the intended behavior?

This came up while troubleshooting import errors using the plugin from lezer-parser/generator which uses virtual modules to load *.grammar.terms imports. I've opened an issue there (lezer-parser/generator#21), but the question that this may be a bug in vitest was raised in that discussion.

Thank you for any assistance & guidance you can provide ❤️
