How to deal insert SQL without columns, such as: INSERT INTO tbl VALUES(?, ?, ?)

If no columns, the insertColumnsSegment.get().getColumns() will return a empty list, and may cause failure.

I forget add the test cases for insert without columns, I will add it soon in other pull request.

[xiyelife]

Yes, I also forget add the test cases for insert without columns。
my purpose is:
in order to use the original order in SQL to rerwite cipher SQL, rather than using the column order in the configured encryption rules, otherwise it will also cause the parameters to be disordered.

I have add test cases of insert without columns in #3299, please run your pr again to verify.
