Problem with nested query

[klahnakoski]

The docs mention a query into unittest.run.files https://github.com/mozilla/ActiveData/blob/dev/docs/jx_tutorial.md#select-clause

{
    "from": "unittest.run.files",
    "select": ["run.stats.bytes","run.files.url"],
    "where": {"and": [
        {"eq": {"build.platform": "linux64"}},
        {"gt": {"run.stats.bytes": 600000000}}
    ]}
}

which appears to fail

Please check if this is a problem with the new cluster, and if so, ensure a test is made

It appears unittest.run.files has been removed. Use the task.artifacts table (which also has a problem.

A better error message is in order for cases when the table does not exist
