rove keeps building up state in the test suite

[AlbertoEAF]

If I use (deftest x ...forms) and then rename x or delete that deftest, the rove package-suite does not erase that.

The test suite for a given package should not keep adding state as at a certain point it has nothing to do with what tests are currently defined. Only works if the LISP system is started, runs rove tests once, and then is closed.

That is not good as launching a LISP system is slow, so the development becomes slower. Rove should allow us to run tests quickly with an ongoing SLIME session or other alive system.

This happens for a similar reason to #49 , the deftest adds the tests to a list of tests instead of replacing the old definitions in the package-suite struct.

Maybe similar issue as #35
