[5.4] Soft delete assertion

[browner12]

• add new method assertion to the InteractsWithDatabase trait
• create new constraint for soft deletes that checks that deleted_at is not null
• a couple of tests for the new assertion

[browner12]

this is my first foray into the testing parts of the foundation, so suggestions are greatly appreciated.

I kinda go back and forth with this. Part of me thinks its simpler to just do like:

$this->assertEquals(1, DB::table('foo')->where()->whereNotNull('deleted_at')->count());

Sorry, wrong button :)

yah, i guess I'm looking at it from the Dusk side of things where everything is trying to be a little more written as you speak it.

I think it comes down to, is it a common enough assertion to wrap it in a nice short method, and I would argue it is.

Thanks,
