    Validate id as integer for os-aggregates

    According to the api-ref, the id passed to calls in os-aggregates is
    supposed to be an integer. No function validated this, so any value
    passed to these functions would directly reach the DB. While this is
    fine for SQLite, making a query with a string for an integer column on
    other databases like PostgreSQL results in a DBError exception and thus
    a HTTP 500 instead of 400 or 404.

    This commit adds validation for the id parameter the same way it's
    already done for other endpoints.
