Ensure WEB-INF directory exists before creating appengine-web.xml

[briandealwis]

Fixes #2250

Something seems off. We call ResourceUtils.createFolders(webInfDir, ...) above.

[briandealwis]

Good point :-) In this case, webInfDir was not null.

I see. So the WTP facet settings (the virtual component) have the WEB-INF directory, but the directory actually doesn't exist, right?

[briandealwis]

I don't quite know how I got into this situation, as the test-projects/springboot-appengine-standard.zip does contain a WEB-INF/appengine-web.xml. I don't recall removing the WEB-INF directory.
