Bugfixing the testcases execusion

tempest.api.compute.servers.test_server_actions\
.ServerActionsTestJSON.test_reboot_server_hard
is working in fuel so do test it.

The "-" was missing so
tempest.scenario.test_server_basic_ops
.TestServerBasicOps.test_server_basic_ops
was executed on fuel which is known to be
not working since metadata service is not
available. That was added already long
ago but through the not adding
of the "-" it got added again.
