Fix #9 after_created hook ordering

[techmahedy]

Change

Updated the insert path in InteractsWithModelQueryProcessing.php so that the model's primary key is assigned before fireAfterHooks('created') is executed, rather than three lines afterward.

As a result, after_created hooks now receive a fully initialized model, and calls such as getKey() or $model->id correctly return the newly created record's primary key instead of null.

Tests

Extended MockHook to capture the result of getKey() from inside the hook callback.

Strengthened testAfterCreatedHook to verify that:

• The key available inside the created hook is not null.
• The captured key matches the model's actual primary key.

The regression test was verified by temporarily reverting the fix and confirming that the test fails with:

Failed asserting that null is not null

The test was then re-run with the fix in place and passes successfully.
