scarb test -f should output tests in a consistent order

[feltroidprime]

Problem

doing multiple scarb test -f pattern outputs the tests in different order each time
this is annoying especially when comparing resources between multiple runs, i want the first test to be the same at each run etc.

Proposed Solution

just sort alphabetically

Notes

thank you

Hi!

This inconsistency stems from the fact, that tests are both executed and results are reported in parallel. (https://github.com/starkware-libs/cairo/blob/96ba347a283aaf197daa918105b5fb4fde8cc403/crates/cairo-lang-test-runner/src/lib.rs#L387)
I don't think we want to wait for all tests to complete before reporting the results.

Quick work-around for now would be to disable parallelism by setting RAYON_NUM_THREADS=1 env var when you really need the ordering of results to be deterministic.
