Error `ShardCollectContext for {0,1,2} already added` in low-memory situations about crate HOT 5 CLOSED

I worked out that PR based on simply reading the code(without reproducible scenario). Still would like to clarify my finding but that would be after producing a fix for this.

On the repository where we originally observed and reported about the problem...

• crate-workbench/mlflow-cratedb#53

... we now just increased the heap size assigned to CrateDB on the CI runner, and we believe the error will go away without further ado.

• crate-workbench/mlflow-cratedb#100
