Setup TLS adaptor when parsing an amqprs uri (#121)

* Setup TLS adaptor when parsing an amqprs uri

* Don't use too new Rust features

* Fix clippy lints

* Fix compiling with urlspec, but not tls feature

* Add test for trying to parse an amqps url without the tls feature
enabled

* Check tls adaptor domain in test

* Remove test that doesn't apply anymore
