datajoint-python Cannot use alter on a part table

Bug Report

Description

When trying to use the alter method on a parts table that is dependent on it's master table, it errors out with DatajointError: Foreign key reference master could not be resolved.

Reproducibility

Include:

Linux
Python Version 3.8.13
MySQL Version 5.7.37-0ubuntu0.18.04.1 (Ubuntu)
MySQL Deployment Strategy local-docker
DataJoint Version 0.13.4
Minimum number of steps to reliably reproduce the issue:

Create a master and part table making sure the master table is a primary attribute of the part table
Add a secondary attribute to the part table
Run PartTableName.alter().

Complete error stack as a result of evaluating the above steps:

DataJointError: Foreign key reference CuratedSpikeSorting could not be resolved

Expected Behavior

Expected a prompt asking if I wanted to alter the table, which would then add the secondary attribute and populate the table with the default value for that attribute.
