Vitest: Incorrect filename when running concurrently

[HalfdanJ]

When using jest-image-snapshots in vitest, the naming of the snapshot files are incorrect when a test suite is run concurrently (describe.concurrent().

Instead of getting the name of each test, it instead gets the name of the last test in the suite, appended with an index, and the order depends on which tests finish first.

I'm unsure if this is a vitest issue or jest-image-snapshot issue.
