Relay always removes files in __generated__ eventhough it has it's artifact directory set to __genenaretd__/relay

[reckter]

We have set the artifactDirectory to src/__generated__/relay, so we can use other code-generater in sibling folders (src/__generated__/something eg).

Relay keeps on deleting these files though whenever run it.

My guess is that it always also checks files in **/__generated__ folders, in order to clean up behind itself eventhough I told it to put it's files somewhere else.

I did not yet test it with another folder name.
