CI: Add unit-test-race

[6543]

to prevent things new races ...

since we can only partially enable race detection we have to add a new task who do not generate a coverage file

once #1441 pass, we can remove this step

[6543]

PS: should fail until #16468 got merged :)

[6543]

If this pull got merged I'll add a revert to #1441
