Subject: Store current input line in history

Regards https://github.com/profanity-im/profanity/issues/200

This doesn't work yet. And I have no idea why.
Weird behaviour:

- start profanity
- type 'ASDF'
- ctrl+arrow down
-> text vanishes (like intended)
- arrow up
-> nothing happens (intended is that the last history item [ASDF]
appears)

- type 'ABC'
- press enter
- arrow up
-> ABC appears
- enter

- type 'UUU'
- ctrl+arrow down
- type 'ZZZ'
- enter
- arrow up
- ZZZ appears
- arrow up
- UUU appears

So in the latter case we added to history and deleted from the input
line and then immediately entered new text and pressed enter, to add
this to the history too.
When we do this the not sent text succesfully was stored in history.
