fix(congestion): fix congestion message formatting
...
It seems that the `~ts` in the format string does not handle maps,
which results in a crash when trying to format the congestion message.
```erlang
28> io_lib:format("~ts", [#{}]).
** exception error: bad argument
in function io_lib:format/2
called as io_lib:format("~ts",[#{}])
```
Example:
```
