The use statement execution code can throw if the keyspace is doesn't exist, this can be a problem for code that will use execute in a fiber since the exception will break the fiber even if `then_wrapped` is used. Fixes #14449 Signed-off-by: Eliran Sinvani <eliransin@scylladb.com> Closes scylladb/scylladb#14394
