New repl command: send-garbage

Browse Source 
This new command attempts to send malformed utf8 string to current chat with
dc_send_text_msg() function. Currently, instead of error code it causes
application crash with following backtrace:

thread 'main' panicked at 'Non utf8 string: '[255]' (Utf8Error { valid_up_to: 0, error_len: Some(1) })', src/dc_t
