cmdlet aliases not always supported in PSCore

[Shashtsoh]

I ran into an issue while training a colleague today. He's using a Mac running PSCore. We couldn't get past the pester version check until we realized that the "sort" command error it was throwing was for the bash sort command. Per PowerShell/PowerShell#6684 the Sort alias for Sort-Object was removed due to the sort command already being present in bash. We edited his dbachecks.psm1 to change "... | Sort Version ..." to "... | Sort-Object Version..." and were able to get past the error.

Aliases should probably be removed for cross-platform compatibility.
