Qt: specifiying -reindex with empty datadir leads to crash #2239

   I had -reindex specified as a leftover from some tests with -txindex and because of the new db directory naming I cleaned my datadir to start an IDB. That case crashed my Qt client right after showing the UI.

   Cause is, that an empty data-dir contains no /blocks/ and no block-files at all but we set fReindex = false not till the import thread is running and fails calling OpenBlockFile(). I guess this is not very nice for bitcoind also.

   Can't reproduce in bitcoind.

   In Bitcoin-Qt, the crash is pindexBest being null in:

   49 QDateTime ClientModel::getLastBlockDate() const 50 { 51 return QDateTime::fromTime_t(pindexBest->GetBlockTime()); 52 }
