Setting "Debug = true" no longer passes errors to client

[JosefWN]

Description

All errors from the server to the client are now "Internal server error" with "server.Debug = true", it used to be detailed error messages, which were very useful in debugging.

Expected behaviour

Detailed error messages.

Actual behaviour

Only the error type is shown.

Steps to reproduce

Cause an error with "Debug = true" set, check on the client side / browser to see the error.

Working code to debug

Something like this should do:

  server := echo.New()
  server.Debug = true
  server.Use(mw.Recover())
  server.Use(mw.Gzip())
  server.Any("/*", func(c echo.Context) (err error) {
    return errors.New("This is my error message")
  })

This issue is back again, I'm not getting any error messages from the server when e.Debug = true.

Another, related bug. If I set "e.Debug = true" and then use subdomains, and also set "server.Debug = true", I'm getting HTTP ERROR NO RESPONSE rather than even the generic "Internal server error". Example:

// ...
e.Debug = true
// ...
  server := echo.New()
  server.Debug = true
  server.Use(mw.Recover())
  server.Use(mw.Gzip())
  server.Any("/*", func(c echo.Context) (err error) {
    req := c.Request()
    res := c.Response()
    host := hosts[req.Host]
    if host == nil {
      err = echo.ErrNotFound
    } else {
      host.Echo.ServeHTTP(res, req)
    }
    return
  })

EDIT: This is the response I get with debugging enabled:

{"message":"Internal Server Error"}

This is not in line with the documentation (https://echo.labstack.com/guide/error-handling):

For a standard error, response is sent as 500 - Internal Server Error; however, 
if you are running in a debug mode, the original error message is sent.

It works if I use echo.NewHTTPError, but this is not something I'm employing in my API:s.
