Visible columns list in table options sidebar does not respect renamed columns

[noahmoss]

Describe the bug
If you change the name of a column in a table, the table options sidebar will still use the original name, not the new name. This can be confusing if all the columns are renamed and you forget how they correspond to the original names (or you weren't the one who renamed them).

To Reproduce
Steps to reproduce the behavior:

1. Go to a table
2. Click on Settings
3. Click on the gear icon for a column
4. Rename the column
5. Go back to the general table settings sidebar
6. Observe that the Visible columns list doesn't use the new name

Expected behavior
The list should use the user-defined column names
