mod_rest: Catch and log errors in callback promise chain
From the code it looks like it should be possible to reply to an error
stanza, but it did not. Turns out I was saved by my local developer mode
module which throws errors if an attempt is made to create an errror
reply to an error stanza. However nothing collects this error from the
promise, so all I got was confusion.
