Invoke-IcingaCheckDirectory doesn't work without filename parameter

[bieba]

The function Invoke-IcingaCheckDirectory doesn't work if you call it without the parameter FileNames set.

Expected Behavior

If you call the function without any filename it should simply return all files within the directory.

Current Behavior

It returns nothing, which is wrong. The directory does contain files.

Possible Solution

Either set it as a mandatory parameter or initialize it with '*' as default.

Steps to Reproduce (for bugs)

1. Make a directory with at least one file in it
2. Use-Icinga
3. Invoke-IcingaCheckDirectory -Path 'C:\PowerShell-Transcription\Processing-Suspicious'
4. (works:) Invoke-IcingaCheckDirectory -Path 'C:\PowerShell-Transcription\Processing-Suspicious' -FileNames '*'

Context

I want to count the files within the directory.
