Refactor: Remove toLowerCase from indexById on Bridge

It shouldn't really change anything and it should allow us to rewrite the indexById as

```ts
static indexById(
list: (T | undefined)[]
): Record {
return this.indexBy(list, 'id')
}

static indexBy, K extends string>(
list: (T | undefined)[],
prop: K
): Record {
return list.reduce((obj, result) => {
if (result) {
const key = result[prop]
obj[key as string] = result
}
return obj
}, {} as Record)
}

```
