[system-tests] ha_sequential_rabbit_master_failover: L754 - IndexError

[Vladimir Khlyunev]

We should use list of roles instead of simple string at https://github.com/openstack/fuel-qa/blob/c1ab3a2d0bc4c06225742f02e9840f0ca7a61f87/fuelweb_test/tests/tests_strength/test_failover_base.py#L755

Reason:
https://product-ci.infra.mirantis.net/job/8.0.system_test.ubuntu.ha_destructive_ceph_neutron/33/artifact/logs/sys_test.log - search for "2015-11-02 01:57:04,131"
