test: stop worker-teardown console race from failing unit shards (#39813)

Vitest rejects a console-log RPC still in flight when a worker tears
down, failing a shard whose tests all passed. Ignore only that rejection
(the lost line belongs to a finished file and passed-only shards drop
it anyway), and stop the two specs seen in CI from spawning real git and
wsl.exe in fire-and-forget background work.
