Merge #15870: wallet: Only fail rescan when blocks have actually been pruned

faf3729242 wallet: Only fail rescan when blocks have actually been pruned (MarcoFalke)

Pull request description:

  This brings the behaviour of the import* calls closer to importmulti. After this change, the difference between importmulti and the other import* calls is

  * that in importmulti you can "opt-out" of scanning early blocks by setting a later timestamp.
  * that in importmulti the wallet will successfully import the data, but fail to rescan. Whereas in the other calls, the wallet will abort before importing the data.
