[Bug-Candidate]: Parsing error when using Medusa corpus

### Describe the issue:

I'm getting the following parsing error when trying to run the tool on a corpus from a Medusa run


and the Foundry test it creates just contains the setup function for the target contract


When using an Echidna corpus it gives no parsing error but creates the same Foundry test

I'm unsure of whether this is due to a misconfiguration on my part or an actual bug in the tool.

### Code example to reproduce the issue:

This repo is the one on which the issue appeared, it uses the default Foundry template and the only thing that's been added is an invariant in the `FuzzCounter` contract: https://github.com/nican0r/fuzz-utils-repro

The `FuzzCounter` contract also includes the commands I used for running the tool along with the command I used for running Echidna. Please lmk if there's anything else I can add that might help.

### Version:

0.0.1
