Describe the bug schema-parse: tranformAbi is modifying the original abi object

Please provide the steps to reproduce and if possible a minimal demo of the problem. Run transformAbi function on any abi and observe the original abi after transformation.

Expected behavior transformAbishould be a pure function and shouldn't do side-effects.
