Mark Stacey c3feabf4de Update SRP representation
An array of integers is now used to represent the SRP in three cases:

* In the import wallet flow, the UI uses it to pass the user-provided
  SRP to the background (which converts the array to a buffer).
* In the create wallet flow, the UI uses it to retrieve the generated
  SRP from the background.
* When persisting the wallet to state, the background uses it to
  serialize the SRP.
