remove old chart mock for getSpecId

The chart ids used to be cast as unique strings (https://github.com/markov00/elastic-charts/blame/8afa62afc4206d8ce3876aa5ccd9c69a8c20518a/src/utils/ids.ts) but this was changed in  elastic/elastic-charts#281 and fully removed in elastic/elastic-charts#554.
