Now that the function has its own test class, the remaining test from `Tests_Block_Template_Utils` can be moved to `Tests_Blocks_GetBlockTemplates` for consistency.

Includes:
* Uncommenting some assertions previously commented out.
* Moving the `get_template_ids()` helper method to the top of the class.
* Standardizing on `wpSetUpBeforeClass()`/`wpTearDownAfterClass()` in both classes.
* Declaring the test theme name as a constant in both classes, since the value is not changed by any of the tests.
* Renaming some properties in both classes for clarity.
