Fix: broken ring-malli-swagger example

[Koura]

Ring-malli-swagger example doesn't compile because malli.core/accept and malli.core/schema-visitor aren't recognized anymore. Remove redundant code block in order to make the example compile.

Thanks, the whole code block seems redundant, could you please remove it?
