ikhal: You get stuck in datetime edit textboxes when removing zero-padding

With the following configured:

[locale]
timeformat = %-H:%M
dateformat = %-d.%-m.%Y
longdateformat = %-d.%-m.%Y
datetimeformat = %-d.%-m.%Y %H:%M
longdatetimeformat = %-d.%-m.%Y %H:%M

You get stuck in these new event "textboxes" when you move over to them:

A way out is to use Page Up/Down or clicking with mouse.

Simply a sed 's/%-/%/g' on the example config above fixes the problem but then it shows all dates and times with zero-padding which I don't want (and with the example config formatting in general doesn't seem to be a problem for the TUI as things display just fine)

I think the least we could do is .replace('-', '') where ever the format is checked.

Start by reproducing the issue in ikhal with the shown locale configuration and inspect the new-event datetime edit textboxes and their format handling. Done means navigation no longer gets stuck with non-zero-padded formats, while dates and times still display without zero-padding.
