Rename column should make the old Object as unused and create a new Object
New derived column should have new Object mapping to it
Dropped column should unlink the Object
Data Wrangler change should not change Attribute/Metric type
Check behavior of interaction between multi-form and Data Wrangler
Facet

Check change data type changes the binning logic correctly
Check update the column changes the binning logic correctly
