send-email: ensure quoted addresses are rfc2047 encoded

Browse Source 
sanitize_address assumes that quoted addresses (e.g., "first last"
<first.last@example.com) do not need rfc2047 encoding, but this is
not always the case.

For example, various places in send-email extract addresses using
parse_address_line. parse_address_line returns the addresses already
quoted (e.g., "first last" <first.last@example.com), but not rfc2047
encoded.

This patch makes sanitize_address stricter about what needs rfc2047
encoding and adds a test demonstrating where I noticed the problem.
