Fix link rendering in auto-close message

[senekor]

I noticed the long link doesn't get rendered correctly, inserting a single space fixes the issue.

#                        just a single space inserted here
#                        v
[this link](very-long-url )

It doesn't happen every time. I suppose there must be something inside the complicated url that confuses github's markdown renderer.

Do you have a link to where the new link format is rendered?

@ErikSchierboom I experimented by editing this message.
