BUG: FastVault creation , Server failed to join

[johnnyluo]

Describe the bug Some user report they can't create fast vault , when they initiate the process on an android device , server didn't join the session.

Potential Root cause:

• It is possible that the mobile device start a session A, but somehow send the request to server with Session B
• Or maybe the ViewModel somehow get executed twice , which result client and server are on two different session
