Swap Genesis State (#960)
* wip: add swap state persistent to genesis

* separate pool record constructors; add tests for json and yaml encoding
of record structs

* beef up validation checks for state records

* fix integration with master - renamed method

* add test coverage for basic state array validations

* extra test around pool record reserve and id ordering to ensure no
regressions in the future

* add validations to ensure pool records and share records are unique
within the collection types

* test genesis json and yaml encoding

* validate in genesis that the total shares owned for each pool is equal
to the total shares of each pool

* update alias

* nit lint

* test genesis init and export

* add migration todo
