PluginDirectoryScanner::getNextPluginFileThatWillBeScanned()

Suggested change to this - to prevent potential crash!

String PluginDirectoryScanner::getNextPluginFileThatWillBeScanned() const
  {
    // Ensure index in range!
    auto theIndex = nextIndex.get();
    if (theIndex == 0) {
        return "";
    }
    theIndex -= 1;

    return format.getNameOfPluginFromIdentifier (filesOrIdentifiersToScan [theIndex]);
}

HTH! Pete
