Sidebar for new events has glitchy-looking whitespace

[jancborchardt]

Compare sidebar for new event (whitespace)

And sidebar for existing event (buttons in place)

→ For a new event where the two other buttons don’t exist yet, there shouldn’t be the whitespace. And note that even for the existing event there are a few pixels of whitespace above the grey line which should not be there.
