[web] Remove logout / delete account / identity login logic from specific reducers

Summary:
issue: ENG-6424
From web specific fields, we only remove in resetUserSpecificStateOnIdentityActions cryptoStore and communityPickerStore. communityPickerStore wan't being cleared on any of those actions before, but it should have been. But that means I only need to update reduceCryptoStore

Test Plan: Tested that cryptoStore is still cleared on logout
