neutron_vpnaas.tests.unit.db.vpn.test_vpn_db.TestVpnDatabase.test_list_endpoint_groups fails due to ordering issue

[Ihar Hrachyshka]

Sometimes the test fails with the following traceback:

    Don't assume the order of endpoints on get is the same as on create

    We don't and should not enforce the order, so enhance the test not to
    assume it.
