Changes to a table's columns can result in role being reset for the entire model

1) Create a project with a single virtual model with the below schema: model1 -> table1a ---> column1a1 ---> column1a2 -> table1b ---> column1b1 ---> column1b2 2) Define a role on the table, removing read permissions from 'column1a2'. 3) Save all changes. 4) Rename column 'column1b2' to 'uselessColumn', leaving a schema like below: model1 -> table1a ---> column1a1 ---> column1a2 -> table1b ---> column1b1 ---> uselessColumn 5) Save changes and synchronize the VDB. 6) Edit data role to see that the permissions have defaulted and 'column1a2' now has read permissions
