Separate out index name and unique constraint name generation in tests.
Review Request #8106 — Created April 8, 2016 and submitted
This updates the test utility functions and data to use separate functions for computing index names vs. unique constraint names. We were formerly generating the unique constraint names by passing default=False to generate_index_name, but this isn't very clear, and isn't future-proof. This change helps get us a step closer to the logic needed for the Django 1.7+ port.
Unit tests pass for SQLite, MySQL, and Postgres.
