fix(connection): fix connection crash when use without web browser

[duyluonglc]

Hi @thetutlage
I have issue when use websocket-client with react-native. After check your code
const wsProtocol = window.location.protocol === 'https:' ? 'wss' : 'ws'
location is undefined because it's not call from web browser.
This PR will fix this issue
Please check when avaialbe

This is just a patch on a short circuit.

The fix should be to stop booting ws client when rendered server side.

I don’t do SSR much, so I am not sure, if there’s a proper way to detect the running environment and add conditionals on basis of that

Okay my bad, you wrote react-native and not ssr. If you are not in a browser, I don't think it will infact work.

The websocket-client relies on the web browser implementation of sockets, so it will fail anyways

Seem the test script failed :(
But I checked with react-native and the websocket works good after remove window.location.protocol from dist file.
Can we detect window.location exists before assign?
const wsProtocol = window.location ? (window.location.protocol === 'https:' ? 'wss' : 'ws') : ''
