fix: bypass error checking for initial migration process

[jmcruz14]

Summary

When attempting to test the available dev-server within the repo via uv run -- python manage.py runserver, Django returns the following error message: django.db.utils.OperationalError: no such table: auth_permission. Attempting to run python manage.py migrate before runserver leads to the same issue.

Currently, the only way to overcome this is to run the migrate command with the --skip-checks flag included.

To ensure consistency with the listed documentation, the fix implements a try/except bypass within src/unfold/checks.py to ensure developers can have an easy installation process for the repo on their device.

Test plan

OS: Sequoia 15.7.1
Python Version: 3.12.2
Django Version: 5.2.14

1. The created db.sqlite3 within tests/server is deleted to ensure a fresh installation.
2. Run uv run -- python manage.py migrate to check if the code change is met.
3. From the root folder, uv run -- pytest . was run to ensure the changes do not break anything else, with the tests executed from my end having shown 417 passed in 19.74s with a total coverage of 95.75%.
