Fixes #211

I have the hunch the error is here: https://github.com/sbt/sbt-buildinfo/pull/208/files#diff-dfebc867528f461dff8d9efe9dac4968b71c28a4efde8c7bd7f5b46371cc5997R40-R41

it got changed from:

extracted getOpt (key in scope(key, project)) map (v => task(ident(key) -> v))

to

extracted.getOpt(project / key).map((v) => task(ident(key) -> v))

but correct would be

extracted getOpt (scope(key, project) / key) map (v => task(ident(key) -> v))

As @adpi2 did in his abandoned PR: https://github.com/sbt/sbt-buildinfo/pull/207/files#diff-dfebc867528f461dff8d9efe9dac4968b71c28a4efde8c7bd7f5b46371cc5997L34-L35

Yea, it seems like I didn't implement / for scope.
