await or return missing on promiseHandler in express.hbs template

[davidsaslawsky-trackinsight]

promiseHandler() returns a promise and should have either an await or a return here: https://github.com/lukeautry/tsoa/blob/master/packages/cli/src/routeGeneration/templates/express.hbs#L103C15-L103C29

The other templates (koa, hapi) are fine. I think it works on Express because it relies on the methods on the response object rather than on the end of the async handler.

Expected Behavior

Current Behavior

It works as expected now but the code is a bit unsafe.

Possible Solution

- promiseHandler(controller, promise, response, {{successStatus}}, next);
+ return promiseHandler(controller, promise, response, {{successStatus}}, next);

or maybe replace promiseHandler() by an await on the controller method: there's the try / catch block calling next(err) anyway.
