Reposotory classes should NOT have caching. It must be possible to access uncached data

[SandGrainOne]

Description of the bug

Storage isn't returning the last version of the texts if the texts happens to have been added to the cache prior to the update.

The issue is noticable in altinn.studio during deploy, if a developer performs two (or more) deploys within 1 hour.

Steps To Reproduce

1. Create a new App in altinn.studio
2. Deploy the App to any environment
3. Make any change to texts
4. Deploy the App to the same environment. This must be done after no more than 1 hour. That is the lifetime of the cache.
5. This results in an exception in studio
6. In Storage we should find a few 409 responses and maybe some "row already exists" errors

Additional Information

The issue here occure because Storage is caching a sort of dummy/empty text representation when there are no texts matching the input criterias. We can keep returning NotFound for an entire hour even though the texts have been added in the mean time.
