This diff adds the condition for removing a keyserver from the keyserver store. I am aware that at this time @inka currently has D9750 and D9820 up which refactor this reducer, and this diff might cause some merge conflicts. @inka and I have been communicating throughout this process and I will make @inka a blocking reviewer for this as well.
