suppress http errors from log if not in debug mode

[yahermann]

It's very common to expect an http error in the course of "normal" (non-erroneous) operation. For example, we sometimes want to check if a resource exists, e.g. GET /some_resource/:id, and we expect to see an http 404 error if it doesn't.

We don't want to pollute the logs with this type of "normal" activity.

Suggested mod, starting in line 807 (https://metacpan.org/release/Web-API/source/lib/Web/API.pm, version 2.6):

if ($error) {
    chomp($error);
    $self->log("ERROR: $error");      #ADD:  if $self->debug;
    $answer->{error} = $error;
}
