    Ignore property errors in implicit dependencies

    Implicit dependencies are calculated before resources are validated.
    Therefore, any error getting a property that occurs during processing on
    implicit dependencies will be raised without any of the context of which
    resource is in error. By ignoring such property errors in implicit
    dependency calculations, we can defer the error handling until the
    actual resource validation and thus give the user an error message they
    can actually use.
