nm-client-error-quark: Active connection removed before it was initialized + Segmentation fault

[tyll]

While testing #60 I sometimes got this error:

nmstatectl set /tmp/nmstate_linkagg_debug-1535467463-FlJO5z

Statefile:

{
    "interfaces": [
        {
            "link-aggregation": {
                "mode": "802.3ad", 
                "slaves": [
                    "eth1"
                ],

            },

            "type": "bond", 
            "name": "web-bond"
        }
    ]
}

Initial state:

nmstatectl show
{
    "interfaces": [
        {
            "ipv4": {
                "enabled": false
            },
            "name": "lo",
            "state": "down",
            "type": "unknown"
        },
        {
            "ipv4": {
                "addresses": [
                    {
                        "ip": "192.168.122.193",
                        "prefix-length": 24
                    }
                ],
                "enabled": true
            },
            "name": "eth0",
            "state": "up",
            "type": "ethernet"
        },
        {
            "ipv4": {
                "enabled": false
            },
            "name": "eth1",
            "state": "down",
            "type": "ethernet"
        },
        {
            "ipv4": {
                "enabled": false
            },
            "name": "web-bond",
            "state": "down",
            "type": "bond"
        }
    ]
}

The error sometimes happen when I do this multiple times:

nmstatectl set <<EOF
{
    "interfaces": [
        {
            "link-aggregation": {
                "mode": "802.3ad", 
                "slaves": [
                    "eth1"
                ], 
                "options": {}
            }, 
            "state": "up", 
            "type": "bond", 
            "name": "web-bond"
        }
    ]
}
EOF

From my observation, this must succeed at least once (see #63) to show the error mentioned here, i.e. the profiles need to exist already.

@tyll , could you please check if #65 resolved this issue?

@tyll , with autoconnect=False and recent changes this should have been resolved.
