Fix eslint rules and types of tests

[Latropos]

Summary

Since we have introduced monorepo code of example application was provided with more restrictive eslint rules, so I have to either fix runtime tests or disable some of the rules. I do both depending on the case.

• Override eslint rule no-template-curly-in-string, because of test-each syntax uses string slooking like string template
• Fix all the type errors, refactor RuntimeTestsApi.ts, to rewrite types of test & describe
• Fix imports and ignore most of other rules

Test plan

Tested on IOS

The name of this PR is a bit misleading because it does more than just fixing monorepo compatibility
