fix(StakeManager.spec): make `epochOnlyIncreases` rule pass 

This was failing due to `migrationInitialize()` allowing for resetting
or decreasing a `StakeManager`s `currentEpoch`.

In practice, however, this is not possible because a new manager can
only be called from an old manager and the old manager can only migrate
once. So if `migrationInitialize()` is called from an old manager, we
can safely assume it's the first time this is called, meaning the new
manager's `currentEpoch` must be `0` at this point in time.
