Perform the migration, even if the current version is not known.

It can happen that user has a very old version with a session, and the mechanism to update the internal data did not exist.
If the user upgrade to a recent version, the migrations were skipped and this can make the existing session not recoverable.

For fresh install, all the existing migrations will be no-op, so that's fine.

Motivation and context

Closes #3534

I confirm that migrating from v0.4.10 is fixing the issue.

The issue was: not restoring the session, and unable to sign in using the same account.
Now: the existing session is migrated and restored, no need to sign in again.
