[BUG] Not Correctly Altering Tables For FKs

**Describe the bug**
The Junction Table should have the Many of the Many-to-One. The screen shot shows the Manys (n) around the junction table. But when I export, 14 of the 16 had the Many's on the opposite side.

**To Reproduce**
Steps to reproduce the behavior:
1. Started off with Blank slate
2. Added Junction Tables and Regular Tables
3. The dragged primary key of Regular Tables To Field that will function as foreign key. (And Vice Versa). Usually the relationship was one to one but fixed to many on the junction table via the references tab.
4. AI helped me figure out why i couldn't import that which i just exported.

**Expected behavior**
FK schema should update

**Additional context**
Add any other context about the problem here. If the bug involves the import feature, please, attach the imported file.

Start by importing or reproducing the schema in BeforeFKFix.sql and ForeignKeyTossUp.sql, then compare the diagram's foreign-key cardinalities with the exported SQL. Trace the junction-table relationship and export/import flow; done means junction tables retain the many-side relationships and the resulting schema imports consistently.
