As per title, basically adding the restart callback path via the fast sync also.
Not tested yet, but the idea is that it removes the conditions of #393 to occur, but I'm not yet fully satisfied (even if it tests OK) because there is still no fundamental way to distinguish between when wallet->load is loading an old but not imported here, wallet, and a currently imported here, wallet.
The latter should use fast because it's much quicker and more reliable, but the former cannot. We probably just need a way for the code to recognize a flag that says "fast sync didn't work", and then switch to detailed sync, in that case, under the hood - and it must remember to do the detailed sync over several iterations, as the CLI scripts do.
