Stop logging TempDirectory IOExceptions in Windows

In Windows, it is generally not possible to remove files that have been
opened in native code in the same JVM process as they were opened. Avoid
logging TempDirectory errors when files cannot be deleted. Robolectric will
attempt to delete them on its next invocation.
