Fix wss urls and session_id lost

[neo87cs]

The current implementation of Ferrum is missing two important points:

1. the ws_url is missing support to wss://..., which is a SSL implementation;
2. cause of subscribers in contexts.rb being async, the context.rb#add_target was loosing the session_id property

can you rebase on main? tests are fixed now.

[neo87cs]

Done, tests are passing now

Sorry to say but linters don't :)

[neo87cs]

I am sorry, i don't know why i thought it was related only to specs, i fixed the lint issue

[route]

There's only single place where we don't pass session id because it's not provided:

@client.on("Target.targetCreated") do |params|
...
@contexts[context_id]&.add_target(params: info)

Theoretically the order of events in Chrome is not deterministic, so it might be called before Target.attachedToTarget happens. If it does we can end up with target w/o session id.

To be precise we should never overwrite session id, so I think condition should be if session_id && target.session_id.nil? but I can correct that. Please let me know If my thinking is correct or you know the way to reproduce the issue. Better to add test.
