## Introduction
Added coverage on the `useDeleteOneRecord` hooks, especially its
optimistic behavior feature.
Introduced a new testing tool `InMemoryTestingCacheInstance` that has
builtin very basic expectors in order to avoid future duplication when
covering others record hooks `update, create, destroy` etc etc
## Notes
Added few comments in this PR regarding some builtin functions I've
created around companies and people mocked object model and that I think
could be cool to spread and centralize within a dedicated "class
template"
Also put in light that unless I'm mistaken some tests are running on
`RecordNode` and not `RecordObject`
Took few directions on my own that as I always I would suggestion nor
remarks on them !
Let me know
## Misc
- Should we refactor `useDeleteOneRecord` tests to follow `eachTesting`
pattern ? => I feel like this is inappropriate as this hooks is already
high level, the only plus value would be less tests code despite
readability IMO
