We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
API tests using wrong tables database
**Describe the bug**
The django API tests are running on the `test_mathesar_db_test_database`, which differs from the `mathesar_db_test_database` tables database we should be using. As a result, we don't have a proper reference to the database being used by the API functions, which prevents us from certain operations like installing types for a test. 

**Expected behavior**
We should ensure `pytest-django` doesn't build a separate tables database.

**Additional context**
Currently blocking #276
