SpecFlowStepDefinitionReport fails with Required option 'p, ProjectFile' is missing as of Specflow 2.4.0

### What You Are Seeing?

When I invoke `SpecFlowStepDefinitionReport` similar to the snippet below:

```
Task("SpecflowStepDefinitionReport")
.Does(() => {
var outputHtml = $"{Environment.CurrentDirectory}/SpecFlowStepDefinitionReport.html";
var reportingSettings = new SpecFlowStepDefinitionReportSettings
{
BinFolder = $"{Environment.CurrentDirectory}/{ParseProjectName(Projects.AcceptanceTests)}/bin/Debug",
Out = outputHtml
};
SpecFlowStepDefinitionReport(Projects.AcceptanceTests, reportingSettings);

var htmlContents = FileReadText(outputHtml);

if (htmlContents.Contains(""))
{
throw new CakeException($"Step definition is not present in any feature file. Please see {outputHtml}");
}
else if (htmlContents.Contains(""))
{
throw new CakeException($"Scenario step is not defined (implemented). Please see {outputHtml}");
}
});
```

It fails with the following error:

```

```

This started happening since upgrading Specflow to 2.4.0, and I assume it is caused by https://github.com/techtalk/SpecFlow/pull/1112

### What is Expected?

It should work just as it used to work before 2.4.0 (e.g. 2.3.2)

### What version of Cake are you using?
0.26.0 / 0.31.0

### Are you running on a 32 or 64 bit system?
64

### What environment are you running on? Windows? Linux? Mac?
macOS

### Are you running on a CI Server? If so, which one?
Local and on CI

Start at the SpecFlowStepDefinitionReport invocation and compare the generated specflow.exe stepdefinitionreport command with the SpecFlow 2.4.0 help output. Reproduce with the shown Cake versions and SpecFlow 2.3.2/2.4.0; done means the report command supplies the required project information and generates the HTML report as before.
