Psalm should reset the cache when changing the error level.

[VincentLanglet]

If I run

psalm --error-level=8

And get no errors

And then I run

psalm --error-level=7

I still get no errors

But if I remove the cache, and run again

psalm --error-level=7

Now I get correctly the psalm errors.

Hey @VincentLanglet, can you reproduce the issue on https://psalm.dev ?

@muglug @weirdan This is a pretty annoying behavior. Any idea about how to fix it ?
Couldn't the cache be written by level ? Like /tmp/psalm/level1, /tmp/psalm/level2, ...
