All Diff Backup pester test are failed

Issue

This is a bug or unexpected behaviour/feature request/new check/question (delete as applicable)

Bug Report

General Troubleshooting steps

• Verified running the latest release of dbachecks?

Does (Find-Module dbachecks).Version match (Get-Module dbachecks).Version.ToString()

• Verified errors are not related to permissions?
• Can duplicate in new/clean PowerShell session (clean = powershell -NoProfile)?

Version Information

• Operating System (Name|Version): Windows Server 2012R2
• PowerShell Version: 5.5.1
• SQL Server (Edition|Version): SQL Server Enterprise 2016 SP1 CU8
• DbaTools version: 0.9.306

Steps to Reproduce

All results from this test are failed. I am sure all the backups are present

$Checks = (
'LastDiffBackup'
)
invoke-DbcCheck -Check $Checks

When I change the markt line in LastDifferentialBackupDate intead of LastDiffBackup it runs fine

This also applies to the full backup test

• Attach any screenshots (if possible/allowed)
• Attach output from PowerShell console (if possible/allowed)

Correct, the same counts for LastFullBackup and LastLogBackup. All checks are using wrong properties from SMO.

I can reproduce it on the newest version 1.1.113
