Currently, the wallet scan progress is not saved.
If it is interrupted, it will be necessary to start from
scratch on the next load.
With this change, progress is saved every 60 seconds.

For the generic wallet tests, make DescriptorScriptPubKeyMans. There are
still some wallet tests that test legacy wallet things. Those remain
unchanged.
No change in behavior. This just moves some code from the ListCoins test
setup to a reusable util function, so it can be reused in a new test in
the next commit.
