* Move user key memory state to state providers
Note: state service observable change is because these updates are no longer internal to the class, but reporter directly to account service through crypto service on update of a user key
* remove decrypted user key state
Note, we're going to move the encrypted cryptoSymmetric key (and associated master key encrypted user keys) as part of the master key service creation. Crypto service will no longer be responsible for the encrypted forms of user key.
* Deprecate notices belong on abstraction
* Allow for single-direction status updates
This is necessary since we don't want to have to guarantee that the update to logged out occurs after the update to locked.
* Remove deprecated subject
It turns out the set for cryptoMasterKey was also unused 🎉
* Expand state provider fakes
- default null initial value for fake states
- Easier mocking of key definitions through just the use of key names
- allows for not exporting KeyDefinition as long as the key doesn't collide
- mock of fake state provider to verify `get` calls
- `nextMock` for use of the fn mock matchers on emissions of `state$`
- `FakeAccountService` which allows for easy initialization and working with account switching
* Small bug fix for cache key collision on key definitions unique by only storage location
* Fix initial value for test
