ci: Split test_tracie_skips_traces_without_checksum in separate cases

test_tracie_skips_traces_without_checksum does the logic previous to
the commit 8546d1dd78. The traces.yml includes
several traces, only the one without checksum is ignored by tracie.

As a complementary action, this change adds an new test
(test_tracie_only_traces_without_checksum) to verify the behavior for
cases where the traces.yml only contains traces without checksum.

Finally, test_tracie_skips_traces_without_checksum is renamed as
test_tracie_traces_with_and_without_checksum
