Change edit dumps format and add indexes for all corpus tests

The new dumped edits format is `edit.<SEED>.<TEST_INDEX>.<SEED_INDEX>.<TEST_NAME>`

To cleanup edits:
- Instead of the standard:
    > rm target/scratch/edit.*

- Use the following shell command:
    > find target/scratch/ -name 'edit.*' -delete
