Fix getting single entity for some endpoints

[noaht8um]

Tweaked following commands so they return the nested object when getting a single item: Get-HuduArticles Get-HuduAssets Get-HuduCompanies Get-HuduPasswords Get-HuduProcesses

This makes getting a single item behave the same as getting multiple items.

The main issue with this is it will be a breaking change for all the scripts that already handle this. I had looked at changing it in the past, but realised it would cause a lot of issues.
