Remove dependency on more-asserts (#4408)

* Remove dependency on `more-asserts`

In my recent adventures to do a bit of gardening on our dependencies I
noticed that there's a new major version for the `more-asserts` crate.
Instead of updating to this though I've opted to instead remove the
dependency since I don't think we heavily lean on this crate and
otherwise one-off prints are probably sufficient to avoid the need for
pulling in a whole crate for this.

* Remove exemption for `more-asserts`
