d31e5c1 Fix shutdown in case of errors during initialization (Wladimir J. van der Laan)

Pull request description:

  PR bitcoin#10286 introduced a few steps which are not robust to early shutdown in initialization.

  Stumbled upon this with bitcoin#11781, not sure if there are other scenarios that can trigger it, but it's good to harden against this in any case.

  E.g.
  ```
  $ src/bitcoind  -debuglogfile=/dfdf
  Error: Could not open debug log file /dfdf
  Program received signal SIGSEGV, Segmentation fault.

  82          g_signals.m_internals->BlockChecked.disconnect(boost::bind(&CValidationInterface::BlockChecked, pwalletIn, _1, _2));
  (gdb) bt
