Actors' lastUpdateTime does not change after update

[Matthew Vaughn]

Here's an extract of an actor record for reference. This entity has been updated several times, but lastUpdated never changes. This makes it hard to trust that the update has gone through when debugging on a rapid iteration cycle.

{ "_links": {
      "executions": "https://api.sd2e.org/actors/v2/w7LMK0k7JGZZQ/executions",
      "owner": "https://api.sd2e.org/profiles/v2/sd2eadm",
      "self": "https://api.sd2e.org/actors/v2/w7LMK0k7JGZZQ"
    },
    "createTime": "2018-04-19 16:32:00.506656",
    "defaultEnvironment": {},
    "description": "",
    "gid": 845002,

    "image": "sd2e/agave-test:dev",
    "lastUpdateTime": "2018-04-19 16:32:00.506656" }
