Expected Behavior

No way for the remote server to induce a panic in the actix-web HTTP client.

Current Behavior

On some websites, e.g. terbit21.wtf, awc panics with the following error:

terbit21.wtf:thread 'main' panicked at 'rustls currently only handles hostname-based connections. See briansmith/webpki#54: InvalidDNSNameError', /home/shnatsel/.cargo/registry/src/github.com-1ecc6299db9ec823/actix-tls-3.0.0-beta.4/src/connect/ssl/rustls.rs:91:14

Steps to Reproduce (for bugs)

1. git clone https://github.com/Shnatsel/rust-http-clients-smoke-test
2. cd rust-http-clients-smoke-test/awc
3. cargo build --release
4. target/release/awc-smoke-test terbit21.wtf

Context

I am testing a bunch of HTTP clients on the top million websites according to the Feb 3 Tranco list.
