Issue Number

Issue #154
PR #259

Overview

This PR makes a number of small fixes to the Cardano.Wallet.DB.StateMachine module:

  • Fixes bug where the incorrect tag was returned from createThreeWallets.
  • Uses consistent naming for maps within Mock.
  • Fixes some small typos in Haddock comments.
  • Extracts out some repetitive function applications.
  • Inlines arguments to readAfterDelete (since it was always called with the same arguments).

The `Mock` data type has the convention that each map has a plural name
based on the type of value held within the map. For consistency with
this convention, the map of wallet ids to private keys should also have
a plural name.

Similarly, we can use `pks` to represent a map, but `pk` to represent a
value within a map.
It previously returned `CreateWalletTwice`, but it should return
`CreateThreeWallets`.
This function is always called with the same arguments, so we can safely
inline these arguments.

Note that this comment wasn't obsolete. It gives a justification for disabling hlint below. Hlint suggests to replace use of concat with ++, but concat reads better :)
