Let ResponseError render w/ 'text/plain; charset=utf-8' header (#1118)

Browse source 
Trait ResponseError originally render Error messages with header
`text/plain` , which causes browsers (i.e. Firefox 70.0) with
Non-English locale unable to render UTF-8 responses with non-English
characters correctly. i.e. emoji.

This fix solved this problem by specifying the charset of `text/plain`
as utf-8, which is the default charset in rust.

Before actix-web consider to support other charsets, this hotfix is
 enough.

Test case:

fn test() -> Result<String, actix_web::Error> {
    Err(actix_web::error::ErrorForbidden("😋test"))
}
