Patch by Robert Scheck <robert@fedoraproject.org> for Zarafa <= 7.1.10 which fixes the RFC-
violating reply of the Zarafa IMAP gateway in response to a failed SEARCH CHARSET request.
This is documented at http://tools.ietf.org/html/rfc3501#page-64: "BADCHARSET: Optionally
followed by a parenthesized list of charsets. [...]". This patch adds missing parenthesis.

Proposed to upstream via e-mail on Sun, 27 Jul 2014 23:58:01 +0200, patch was put into the
upstream ticket https://jira.zarafa.com/browse/ZCP-12504.
