Duplicate base error

[behlbor]

If a table has two fields with links to records from a second table with backlink option selected, then an error occurs when duplicating the database:
Raw query failed. Code: 42701. Message: ERROR: column "table2" (second table's UI name) of relation "New_table" (first table's db name) already exists

Steps to reproduce the behavior:

1. Create base with two tables
2. Add to first table two fields with links to records from second table with backlink option selected
3. Duplicate base
