500s encountered with latest develop branch due to #2890

[pavish]

Description

• Pull the latest develop branch over an existing Mathesar instance (which had the migrations already applied prior to the changes from Updated datafile model to store file type #2890).
• All requests to tables fail.
• I assume this is because Updated datafile model to store file type #2890 modifies 0001_initial.py migration file, instead of adding a new one.
• This will affect all upgrades.

Environment:
