Fix login detection on new LAVA versions
Fix login detection on new LAVA versions

In LAVA versions greater than 2020.02 "auto-login-action" has been
renamed to "login-action". There is a need to handle both cases hence
there are labs using older and newer LAVA instances. This fix makes
KernelCI backend treat "login-action" or "auto-login-action" as a valid
test case indicator depending on which one is present in the "lava" test
suite provided by callback JSON.
