Trim trailing spaces in error replies coming from rejectCommand (#7668)

Browse Source 
fe8d6fe749 added rejectCommand which takes an robj reply and passes it
through addReplyErrorSafe to addReplyErrorLength.
The robj contains newline at it's end, but addReplyErrorSafe converts it
to spaces, and passes it to addReplyErrorLength which adds the protocol
newlines.

The result was that most error replies (like OOM) had extra two trailing
spaces in them.
