Slow/Hyper adding/removal affecting Calm

[elias098]

I am not completely sure if this is correct or not.

Before https://github.com/pmotschmann/Evolve/commit/4ea8757c13226246694bdfe7d369594c5f8a417c calling cleanAddTrait and cleanRemoveTrait on slow/hyper reloaded the page, but that got changed to restarting the web worker instead.

This change caused the addition and removal of slow/hyper to run the next code block in the switch statement, thus running the code for adding and removing calm.

Adding a break at the end of the slow/hyper code blocks should fix this issue.
