bitcoin-qt core dumps when bitcoin(d/-qt) is already running #10815

   On master at 7666250

   It's expected to just exit cleanly with an error message that it can't obtain a lock on the data directory. Instead it shows that error message and then when you click it away it core dumps.

   This doesn't happen with bitcoind.

   This also results in losing RPC credentials to the running bitcoin(d/-qt)

   This problem happens because Shutdown() is called, even though the data directory was not locked.

   Most easily reproducible in the GUI, though it's also possible to happen with bitcoind in a rare race condition (if the check in AppInitSanityChecks succeeds, but the lock can't actually be grabbed in AppInitSanityChecks and that exits with false, it will fall through and call Shutdown).
