Fix api utils test and improve test coverage

[ryanchristo]

We are currently skipping a test within src/api and in total have 4 tests within this repository. We should consider improving the test coverage after resolving the current issue within src/api:

// TODO - valtio messes this up
describe.skip('Group Transforms', () => {
  it.skip('works on normal chain group', () => {
    expect(toUIGroup(stubGroup)).toEqual(stubUIGroup)
  })
})
