Fix ui handlers & state sync for task enabled checkboxes

Refactor toggle checkbox & delete handlers to typed class
instance methods in KapacitorRulesTable & TasksTable, and
to use traditional, testable JavaScript syntax.

Remove curry in KapacitorRulesPage component methods to
successfully toggle & delete, in accordance with above
refactor.
