In some conditions we just returned without freeing allocated variables.
Should fix following valgrind reported leak:
```

```
We call omemo_init() when starting profanity and should have an
omemo_close() at exit.
For now we free the fingerprint autocompleter in there.
Fixes valgrind:

Probably missing copy of body to plain in carbon and privmessage.
Only covers the incoming message path because goal is OMEMO decryption
of untrusted message.
Cover some of the log functions but not all.
Implements feature requested at: https://github.com/profanity-im/profanity/issues/632
So instead of:
/time console set <format>
/time chat set <format>
/time muc set <format>
/time mucconfig set <format>
/time private set <format>
/time xml set <format>
As a short cut the user can do:
/time all set <format>
Excluding statusbar and lastactivity settings since they are not for main windows, but used slightly differently.
