Artifacts: filtering by range is not working as expected

[Alexander Tivelkov]

According to spec, the list artifacts API call should be able to list artifacts by the range of some of its property, if the property supports comparison, e.g
/v3/artifacts/some_type/?property=gt:1&property=lt:10
 should return all the artifacts having the value of "property" greater than 1 and less than 10.
However this does not work: greater than 1 part is ignored and only the last condition is applied.

    Allow to filter artifacts by range

    This code enables filtering properties by range by providing
    several parameters, that now considered as concatination,rather
    than using only the latest one.

    Example: /v3/artifacts/some_type/?property=gt:1&property=lt:10
    Returns all the artifacts having the value of "property" greater
    than 1 and less than 10.
