Avoid expensive formatting for simple messages

[ericf]

This avoid expensive message formatting for simple messages without values. In development messages will always be formatted in case of missing values that are suppose to be there.

This should drastically improve performance, both memory and CPU, for all apps.

This is going to help a ton! Thanks @ericf. 👍

looks good but maybe we should just wire this up at the beginning of the method, not need to skip a bunch of conditions if no values are provided, and we are in prod. from the current diff it is difficult to imagine that this is a short circuit process, you have to read the whole thing to encounter that it reality it is just falling back to message.

@caridy yeah the early return makes the diff much easier to read. I updated to use that instead.
