Lockfile is never up-to-date in Pixi version 0.39.0

Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

$ pixi --version
pixi 0.39.0
$ pixi install
✔ The default environment has been installed.
$ pixi install --locked
  × lock-file not up-to-date with the project

Issue description

Somehow, pixi install thinks the lockfile is outdated, when it isn't on the newest version (0.39.0)
This does not happen in version 0.38.0.

Expected behavior

The lockfile should be up-to-date after running pixi-install.

Hey @RaphaelMelanconAtBentley , would you be able to share the project you are experiencing this with?

I tried on jupyterlab and pypi examples and so far it seems to be fine. Did pixi install touch (update) your lockfile? Maybe it has to do with the version of the lockfile of your project (which would still be a bug!).

Humm, then maybe the sequence to reproduce is more complex...

I was using version 0.38.0 with and existing lockfile.
Then, I updated to 0.39.0, made some changes to my pixi.toml and reinstalled.
That's when the issue began.

I'll try to reproduce and let you know. Otherwise, it may have been a fluke.

I was not able to reproduce... Must be a very specific sequence of actions to trigger this. Will reopen if I run into this again.
