2981: Move index swap error handling from meilisearch-http to index-scheduler r=irevoire a=loiclec

And make index_not_found error asynchronous, since we can't know whether the index will exist by the time the index swap task is processed.

Improve the index-swap test to verify that future tasks are not swapped and to test the new error messages that were introduced.
