The generators were doing crypto operations - which are really slow and generally not required for test cases.
It was ignoring the scale parameter and therefore generating excessively long names.

2664: Fix slow ApiSharedWallet unit tests r=paweljakubas a=rvl ### Issue Number Found during ADP-902 ### Overview The `Cardano.Wallet.Api.Types` tests are running very slowly. Also the unit tests were sometimes timing out in CI. Profiling showed that the `Arbitrary` instance of `ApiSharedWallet` was the slowest part. This change improves the speed of this generator. Now it is the OpenAPI validation which is the slowest part. ### Comments We may also be able to reduce the size of arbitrary `ApiSharedWallet` values, so that validation gets faster. Because it's still not especially quick. Something like the `instance Arbitrary WalletName` change in this PR could probably be applied. Co-authored-by: Rodney Lorrimar <[email protected]>
