[UX] Fix sky jobs logs for finished jobs

[Michaelvll]

sky jobs logs has an issue with finished jobs as we did not expand the log files with username. In this PR we fixed it.

To reproduce:

sky jobs launch -n jobs-logs --cloud aws --cpus 2 echo hi
sky jobs logs

Tested (run the relevant ones):

• Code formatting: bash format.sh
• Any manual or new tests for this PR (please specify below)
• All smoke tests: pytest tests/test_smoke.py
• Relevant individual smoke tests: pytest tests/test_smoke.py::test_fill_in_the_name
• Backward compatibility tests: conda deactivate; bash -i tests/backward_compatibility_tests.sh

Actually this is not the case. The jobs logs works fine on master. False alarm. Closing.
