[next?] Special stage pits act like exit sectors in special stages instead of special stage pits

This was recently discovered by Wumbo while playing SRB2 the Past in what I assume to be a [next] branch of SRB2. They jumped over the pit and it acted like they failed the special stage

This issue doesn't occur in the released 2.2.10 version of SRB2 as shown here:

and I can only assume something got messed up in the code as this is the normal set up
