feat(react): getSession

[inshatan]

Reasoning 💡

The changes cover following issues:

• getSession call does not trigger session object update until window loses focus #596
• useSession/Provider does not update when a new session is created until page reload. #2208

When retrieving session on the client with the method getSession it is reasonable to update the data stored in the context

getSession is intended to be an isomorphic method that works both client and server-side, and likely won't have the capability to update the state, as it is often used outside of React lifecycle methods even on client-side. For that, please rely on useSession, and well, on the server-side this wouldn't make sense anyway.

Thank you for the quick reply)

The proposed changes will remain getSession isomorphic.

About the issues - currently, you should reload the page to update the session. It is inappropriate in a lot of cases.

There is a workaround: #596 (comment). But this workaround will not work when a user is unauthenticated (__NEXTAUTH.session = null).

Please provide some mechanism to trigger session reload/update programmatically. I can help you with implementation if it is necessary.
