The service-get-log command returns always the same output ignoring
the 'server' filters.
This fix avoid returning all the results when using the 'server' filter.
How to reproduce:
'cinder --os-volume-api-version 3.52 service-get-log
--server localhost.localdomain@cep'
return the same output than
'cinder --os-volume-api-version 3.52 service-get-log'
Also includes squash to fix unit test from:
