Add test for addrman consistency check on restart with asmap

PR #22697 introduced a reproducible issue in commit 181a1207 that causes the
addrman tried table to fail consistency checks and significantly lose peer
entries when the `-asmap` configuration option is used.

The issue occurs on bitcoind restart due to an initialization order change
in `src/init.cpp` in that commit whereby CAddrman asmap is set after
deserializing `peers.dat`, rather than before.

Issue reported on the `#bitcoin-core-dev` IRC channel starting at
https://www.erisian.com.au/bitcoin-core-dev/log-2021-08-23.html#l-263.

```
addrman lost 22813 new and 2 tried addresses due to collisions or invalid addresses
ADDRMAN CONSISTENCY CHECK FAILED!!! err=-17
bitcoind: ./addrman.h:707: void CAddrMan::Check() const: Assertion `false' failed. Aborted
```

How to reproduce:
- `git checkout 181a1207` and recompile
- launch bitcoind with `-asmap` and `-checkaddrman=1` config options
- restart bitcoind
- bitcoind aborts on second call to `CAddrMan::Check()`

This commit adds a regression test to reproduce the case; it passes or fails
with the same error.
