Remove pytest deprecation warnings by upgrading Flask-SqlAlchemy

[tmpayton]

What we’re after

The Flask upgrade has caused deprecation warnings when running pytest. This issue is coming from Flask-sqlalchemy. To fix this we need to upgrade flask-sqlalchemy.

Warnings: DeprecationWarning: '_app_ctx_stack' is deprecated and will be removed in Flask 2.3. Use 'g' to store data, or 'app_ctx' to access the current context.

DeprecationWarning: 'propagate_exceptions' is deprecated and will be removed in Flask 2.3.
