fix(router/expressions): http redirection can't work with "expressions"

[chronolaw]

Summary

KAG-1251

This is a follow up of #11082.

if route.protocols has only https, we will not add net.protocol to expression.
This will give the runloop a chance to check http redirection.

Note:
Now expressions does not support tcp/tls, so we skip these test cases.
