DBTest.DynamicLevelMaxBytesCompactRange: make sure L0 is not empty before running compact range 

Summary: DBTest.DynamicLevelMaxBytesCompactRange needs to make sure L0 is not empty to properly cover the code paths we want to cover. However, current codes have a bug that might leave the condition not held. Improve the test to ensure it.

Test Plan: Run the test in an environment that is used to fail. Also run it many times.
