Global algorithm parameters are not removed properly
- I fork an experiment that uses a given algorithm (e.g. tutorial/pca/1),
- Replace this algorithm (e.g. by tutorial/pca/2) (3. This algorithm is not used by any other block of the experiment)
Then: I am unable to run this experiment, and I get the following alert message: (...) The experiment isn't valid, since (...) globals: found parameter section for algorithm `tutorial/pca/1' which is not used anywhere in the experiment.
