Running the tests of 0.1.6 produces `got an unexpected error: There is no property called "Changes_When_Casemapped"`

Does anyknow know what's going on? This is how I run the tests:

```
	sbcl --non-interactive \
	     --eval '(require "asdf")' \
	     --eval "(push #p\"${wrksrc}/\" asdf:*central-registry*)" \
	     --eval '(asdf:load-system "cl-unicode/test")' \
	     --eval '(uiop:quit (if (cl-unicode-test:run-all-tests)
	                          0 1))'
```
