Invalid config queries should not be added to database

[jdtzmn]

Posting to /bid with invalid server_config_query responds with a 500 status code, but the invalid query is still added to the database.

For example, the following server_config_query would respond with a status code of 500:

[
    [
      [
        "cpu_type",
        "contains",
        "intel"
      ],
      [
        "cores",
        ">=",
        "4"
      ],
      [
        "RAM_GB",
        ">=",
        "8"
      ],
      [
        "storage_size_GB",
        ">=",
        "512"
      ]
    ]
  ]

Later, when getting /bid, a 500 status code is shown because the flocx-market code is expecting a dict instead of an array. See the stack trace for more information.

There should be input checking for server queries to ensure that one can always see the existing bids.

@jdtzmn if this still reproduces, can you include the stack trace here? The link in your original report has expired.
