util.jid: Fix special escaping of '\' per XEP-0106 From XEP-0106 §2. Requirements: > in certain circumstances, the escaping character itself ("\") might > also be escaped Later in §4.2 Address Transformation Algorithm it is stated that the backslash would only be escaped if it forms an escape sequence. Thus '\foo' is unaltered but '\20' must be escaped into '\5c20'. Thanks to lovetox and jonas’ for brining up.
