ipatests: remove fixture call and wait to get things settle

system date moved in order to expire the certs. Sometime it
is observed that subsequent operation fails with 500 error for CA,
hence restart the services after moving date and wait for sometime
to get things settle.

Also the tests was calling fixture which is not required for it, hence
removed it as well.
