Non US-ASCII characters in display name parsed incorrectly by InternetAddress(String)

Non US-ASCII characters end up **unencoded** in _encodedDisplay_ field when constructor InternetAddress(String) is used to parse valid addresses e.g. `"тест" `.

The workaround is to use InternetAddress(String address, String display) or InternetAddress(String address, String display, String charset)

Start by reproducing the reported address parsing with InternetAddress(String), then compare its behavior with the overloads that accept a display name and charset. The work is done when valid non-US-ASCII display names are correctly encoded in the encodedDisplay field without requiring a workaround.
