Properly display chatwin history

So far if one had enabled `/history` and did `/msg somenick` the history
was loaded from file and displayed like this:

```
04-04-17 15:23 - 3/4/2017:
01-01-00 10:30 - me: ....
01-01-00 10:31 - somebody: ....
01-01-00 10:32 - somebody: ....
```

So the first line contained the actual date. But the date used in each
line was always 01-01-2000. This date was for some reason hardcoded.

This commit now actually uses that date to build the proper GDateTime
instead of just printing it.

Fix https://github.com/profanity-im/profanity/issues/922
