Skip TestExportAndImportMultiLayer on Windows
Skip TestExportAndImportMultiLayer on Windows

This change skips the TestExportAndImportMultiLayer in integration/client
for the time being. It seems the image was updated recently and no longer
has a Windows entry in the manifest so the test will always fail. This should
be reverted when we figure out what happened to the image, but this is to
unblock PRs for the time being.
