[Bug]: Different stats report at the and with vs without `--parallel`

[PKeidel]

What Happened

We use pest in a new project and we are somewhat irritated. In the metrics at the end, there are different values been reported, when we compare with and without --parallel .

I would assume that these numbers should match exactly.

How to Reproduce

Run tests twice, with and without --parallel:

/app# ./vendor/bin/pest | grep -A5 'Tests:'
  Tests:    2 deprecated, 1 skipped, 821 passed (2073 assertions)
  Duration: 4.85s

/app# ./vendor/bin/pest --parallel | grep -A5 'Tests:'
  Tests:    1 skipped, 455 passed (2073 assertions)
  Duration: 4.11s
  Parallel: 7 processes
