Fix incorrect type reference and improve error formatting in ABI error generation

[Marcofann]

This pull request fixes a logic issue in the NewError function where the incorrect input.Type reference was used instead of inputs[i].Type after potentially modifying the inputs slice. This ensures the correct type is always used when generating the string representation of the error.

Changes

• Corrected type reference from input.Type to inputs[i].Type in NewError.
• Updated the invalid identifier error message in Unpack to improve readability and consistency.
