Small refactor of lock.component (#3325)

* Extract method for unlockWithPin

* Extract method for unlockWithMasterPassword

* Switch condition and use early return

* Moved logic that belongs together closer together

* Make unlockWithPin and unlockWithMP private and move them below the public methods

* Extract to new method handlePinRequiredUnlock
Remove kdf and kdfIteration params

* Extract to new method handleMasterPasswordRequiredUnlock
Remove kdf and kdfIteration params
