## Summary

Adds initial set of end to end tests for lists

You can run all of these with the command from kibana root:

```ts
node scripts/functional_tests --config x-pack/test/lists_api_integration/security_and_spaces/config.ts
```

Fixes a few minor bugs found such as...
* Validation for importing lists was not checking if the indexes were created first
* Some wording for the error messages had duplicate words within them
