Fix socket.io error

[thani-sh]

Socket io requires a hack where we should set the window.navigator.userAgent to something. But in react-native that property is read only so it throws an error.

It also throws an error if the hack is not included.

Try to fix the issue or replace socket.io with something else.

The fix didn't work. It might have worked when tested for some unknown reasons.

Could get it to work by using a patched socket.io until they make an official release The issue was on engine.io-parser repo and they have already merged the PR with the fix. But they still haven't done a release. Until the fix is on an official release, used this patched version.
