Random generated input for a route parameter should not start with a forward slash #8
Description
If I have a route for /my_endpoint/{string:my_input}, swaggercheck should nog generate input for it that starts or includes a forward slash, as it's no longer testing the endpoint, but creating a different route by doing so.
ex
/my_endpoint//randominput
/my_endpoint/random/input
/my_endpoint/ra/ndomi/np/ut
These will all return 404 because flask cannot route them to the correct view.
