[TIMOB-17008] An additional folder 'template' gets added to the project if some of its platforms are checked after creation from the tiapp.xml file

1. Create a default Titanium project or any template project (like single window) for all Platforms. 2. Now uncheck some platform while creation and than create a project. 3. After the project gets created select the unchecked platforms from Tiapp.xml file and save it. Actual Result: 1. The 'template' folder does not get created for a project which is created for all platforms. 2. The project which is created for selected platform firstly does not have any template folder but once the unchecked platforms are selected from the Tiapp.xml file and saved, a new 'template' folder gets added to the Project folder hierarchy. This 'template' folder also has a 'Resource' folder and 'app.js' file in it. So the same project has two Resource folders as well as two app.js files.
