Fix ComputeTimeSmart test failure with -DDEBUG_LOCKORDER

Browse Source 
Failure looks like:

    Entering test case "ComputeTimeSmart"
    test_bitcoin: sync.cpp💯 void potential_deadlock_detected(const std::pair<void*, void*>&, const LockStack&, const LockStack&): Assertion `false' failed.
    unknown location(0): fatal error in "ComputeTimeSmart": signal: SIGABRT (application abort requested)
    wallet/test/wallet_tests.cpp(566): last checkpoint

Reproducible with:

    ./configure --enable-debug
    make -C src test/test_bitcoin && src/test/test_bitcoin --log_level=test_suite --run_test=wallet_tests/ComputeTimeSmart

Happens due to "92fabcd443 Add LookupBlockIndex function" which acquires
cs_main from inside CWallet::ComputeTimeSmart.
