New concept not available on c11y/concepts endpoint

[bobvanluijt]

How to reproduce:

GET http://localhost:8080/v1/c11y/concepts/kubectl

Result (i.e., not found, we might actually want to show that):

{
    "individualWords": [
        {
            "word": "kubectl"
        }
    ]
}

then: POST http://localhost:8080/v1/c11y/extensions with data object:

{
  "concept": "kubectl",
  "definition": "The CLI tool to administer Kubernetes clusters",
  "weight": 1
}

Now, when running GET http://localhost:8080/v1/c11y/concepts/kubectl again. The result is still:

{
    "individualWords": [
        {
            "word": "kubectl"
        }
    ]
}

The expected result is to find the actual data objects related to a word that's found.
