Verify the inactive Cr50 header on the first login after cryptohome restarts.

There are two special cases this test covers: logging in after the TPM owner is
cleared and logging in as guest. After the tpm owner is cleared, corrupting the
header will be done on the second login. During guest login the owner wont be
cleared.
