Releases wallet shared pointers prior to doing the final settings update and prevent GUI races trying to access a wallet that is no longer loaded.
And update function's documentation.
Multiple threads could try to delete the wallet at the same time.

Code review ACK 7a73b0b7d5e690235bcefca9b82f01442b37ad5e. This is a much cleaner bugfix than I suggested in #29073. Moving the unload notification makes the shutdown sequence easier to understand, more efficient, and safe.

To better describe the function's behavior. And add wallet name to logprint.

Coming from #29073.
Applied ryanofsky suggested changes on #29073 (comment) with few modifications coming from #18338 (comment).
The only point I did not tackle from #18338 (comment) is:
Because it would mean every
CWalletobject would flush data to disk during destruction. Which is not necessary for wallet tool utilities and unit tests.
