Issue Description:

Test Case 'ManifestTests.testManifestLoading' started at 19:03:04.628
<unknown>:0: error: error parsing input file '/tmp/TemporaryFile.GtuKll' (expected top-level entity)
Can't parse Package.swift manifest file because it contains invalid format. Fix Package.swift file format and try again.
/home/buildnode/jenkins/workspace/oss-swift-3.0-package-linux-ubuntu-15_10/swiftpm/Tests/PackageLoadingTests/ManifestTests.swift:79: error: ManifestTests.testManifestLoading : failed - Unexpected error: invalidManifestFormat(nil)

We might have pushed a patch already for this in master, and if so, we just need to merge it into swift-3.0-branch.
