Due to an oversight, when users use an unexported declaration from implicit global module, the diagnostic will show "please #include" instead of "please import". This patch corrects the behavior. Also previously, when users use an unexported declarations from module partitions, the diagnostic message will always show the partition name no matter if that partition name is visible to the users. Now the users may only see the partition name if the users are in the same module with the partition unit.
