Xcode 8 Support / copy expected test class name

[kenji21]

Hi Mark,

Just fixed a crash on xcode8 for your plugin
Two commits because the first adds the feature : I want to copy test class name when no test file are found

To make plugin work with xcode8 on Sierra, i run this script :

#!/bin/bash

if [ $# -lt 1 ] ; then
        echo "usage : $(basename $0) /Application/Xcode.app";
        exit -1
fi

XCODE_APP_PATH=$1

/usr/bin/codesign --force --sign "Mac Developer" --timestamp=none /Applications/Xcode.app
/usr/bin/codesign --force --sign "Mac Developer" --timestamp=none /Applications/Xcode.app/Contents/PlugIns/IDEDocViewer.ideplugin

/usr/bin/codesign --force --sign "Mac Developer" --timestamp=none ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins/*.xcplugin

Found an issue with short file name and fixed test, so added some commit this morning

Sorry I haven't got around to looking at this in depth. I'll merge it and may make some minor tweaks to it this week. Thanks!
