Add a check to ensure that we find crypto data in the crypto store
when we're restoring a session and otherwise abort the session restore.
This will prevent us from restoring a session and generating new keys
when there was a previous session with different keys.
***This will force a logout for all users***
See the linked issue (and the comment in code) for more detail.
Fixes https://github.com/vector-im/element-call/issues/464
The recent typescripting appears to have caused the typescript
compiler to get confused about dependency references and start
refwrencing things like CRYPTO_ENABLED in the js-sdk before it's
defined them.
This avoids using things from the (javascript) browser-index import
and instead pulls everything in from the typescript files, then
fixes the resulting type failures, (in some cases with hacks).
