Rebuild Keep module after toggling all/any

[dehall]

Addresses #19 - Rebuilds the Keep Module after toggling the Any Of/All Of switch.

To Reproduce (from linked issue):

• Start with the ALL OF / ANY OF toggle set to ALL OF.
• Define some set of Keep Module Builder criteria (e.g. add some active conditions)
• Download the Keep.json file and inspect it: default state should have states.Initial.conditional_transition[0].condition.condition_type == 'And'
• Return to the Keep Module Builder and toggle the ALL OF / ANY OF to the ANY OF state.
• Download the Keep.json file and inspect it: states.Initial.conditional_transition[0].condition.condition_type should now be "Or"; previously it was stuck on "And"

Note this doesn't add any debounce as suggested in the issue, that's something to tackle when we have more time

Note: CI was already failing on master with a lot of linter errors so I'm not going to worry too much about that at the moment
