[PATCH] test: Canonicalize RFC 2047 encoding and charset

[Austin Clements]

RFC 2047 states that the encoding and charset in an encoded word are
case-insensitive, so force them to lower case in the reply test.  This
fixes an issue caused by GMime versions (somewhere between 2.6.10 and
2.6.16), which changed the capitalization of the encoding.
