Shorten the name of groupchats to overcome truncation bug

The names of groupchats are truncated internally to 22 characters.
This causes many problems with groupchats, since spectrum incorrectly
identifies the chat by the long name.

To overcome this the phoneNumber-unixTime is converted to hexadecimal,
to shorten the groupchat below 22 characters
