UIY-3913 Change routes for system calls

Previously, the "count" function was executed on all
directory levels (""/", "/a/", "/abc/", etc).
This meant that you could not successfully mock a request
to e.g. "/bla/?foo=bar", because you'd end up on
the count-action. Moving all those system calls to
/api-mock/... prevents those issues.
