sub projects belong to wrong folder in explorer

[jdneo]

          I found an issue about this change that some of the modules are in the wrong place:

For example, here: the app and mylibrary should belong to android-test.

Clone and open the project https://github.com/microsoft/build-server-for-gradle can reproduce the error

@jdneo I will have a look at this and provide a fix.

@jdneo I was ignoring the option gradle.nestedProjects: true and did not test with it. With this option in mind, it is clear to me why my solution causes this issue. I provided a fix here: #1617

I was also surprised why it does not show more builds/projects for the https://github.com/microsoft/build-server-for-gradle repository, which I think it should. Here is a proposal to change that: #1618

Thank you! I'll look at them ASAP.
