Title: #5680: ipatests: Skip test_jsplugins in server-less environments
This test assumes that IPA server is installed and configured.
But test_jsplugins is the subtask of fasttest which is designed
(unittest) to be run in server-less environment.
Note: `needs_ipaapi` is not completely suitable because there is
no direct IPA API usage. `xmlrpc_setup` fixture is also not
suitable because it assumes XMLRPC.
