How to reproduce:
1. Open attached project
2. Check that 'Scripting Define Symbols' is set as 'myDefine' on android platform
-- The define is marked with a star ( * ), which indicates that it is a shared setting between platforms
3. Enter playmode using standalone platform -> Nothing printed in the console
4. Enter playmode using android platform -> print out in the console due to custom define

Expected behaviour: Setting 'Scripting Define Symbols' not marked with a star as 'shared setting'
