closes #2713

Short description and why it's useful

Fixes problem with infinite redirections and redirections on SSR on account site. What has been done:

• changed user/startSession to async method and awaits its invocations
• make sure in router/beforeEach that local session data are readed before redirecting to home page
• do not redirect to home on SSR render on auth site, using NoSSR for session-related data and no more blinking home->account (and no hydration issue with that change)
• startSession only once with reading localStorage data, there were many requests with multiple invocations and slowed down initial render
• user data in localstorage are kept on single key, removed prefix causing problem with reading local session after changing language

Just some naming minor issues

[pkarw]

It should be named like “local_session_started” or “local_session_loaded”

/ - missing char in the mutation name

Hello,
I have tested it is working (solving the refresh issue) on default theme,
but not the vuetique theme. (it will reload, with no content generated (only showing the my account navigations, and all the buttons are unabled. )

Any idea of the related file that causing the difference?
thanks
