send-email: use sanitized address for cc

From: "Du, Changbin" <[email protected]>

Some username in the email address may include a ','. In this case, we need quoting the username field so it will not be parsed as two single addresses by Mail::Address->parse().

For example, my eamil address "Du, Changbin <[email protected]>" can be parsed as two addresses "Du" and "Changbin <[email protected]>" if username is not quoted. ("Du, Changbin" is a legal format of signature in Chinese)

The sanitized address can be used because quote is added automactically.
