An already merged rowset should skip window check

[wangbo]

When I upgrade one be from 0.12 to 0.13.11, I found log as below:

W1224 14:33:37.902747 407046 cumulative_compaction.cpp:94] There are missed versions among rowsets. prev rowset verison=[254211-304122], next rowset version=[304141-304141], tablet=1270127.782010313.8f4b94bfeec38b2c-4f09624a4825959a

It seems that rowset [304123-304140] is missed.
But the truth is [304122-304140] is already merged and its create time is updated when merge finished.
So its create time is even later than [304141-304141].

rowset [254211-304122] merge time:

I1224 14:32:55.143887 407047 compaction.cpp:117] succeed to do cumulative compaction. tablet=1270127.782010313.8f4b94bfeec38b2c-4f09624a4825959a, output_version=254211-304122, segments=5. elapsed time=0.054334s.

rowset [304123-304140] merge time:

I1224 14:33:21.115556 407038 compaction.cpp:117] succeed to do cumulative compaction. tablet=1270127.782010313.8f4b94bfeec38b2c-4f09624a4825959a, output_version=304123-304140, segments=3. elapsed time=0.041287

rowset [304141-304141] create time

I1224 14:32:53.966773 407106 engine_publish_version_task.cpp:114] publish version successfully on tablet. tablet=1270127.782010313.8f4b94bfeec38b2c-4f09624a4825959a, transaction_id=21035995, version=304141, res=0

The miss version log is really confusing, I think a already merged rowset shouldn't be checked by config::cumulative_compaction_skip_window_seconds
