Resolve Minitest 6 deprecation in assert_no_changes
These changes resolve a deprecation warning in `assert_no_changes`
when asserting that an expression evaluates to `nil` before and after
the passed block is evaluated.
The smallest demonstration of this edge case:
```ruby
assert_no_changes "nil" do
true # noop
end
```
Under the covers, this is evaluating
```ruby
assert_equal nil, nil
```
Minitest 5 issues a deprecation warning, and Minitest will fail
completely.
For additional context, the motivations and implications of this change
to Minitest have been discussed at length in [seattlerb/minitest#666][].
