PSSA v1.18 is giving errors with subclasses

[ykuijs]

Details of the problem, bug, or enhancement

With the release of PSScriptAnalyzer v1.18, several resources in SharePointDsc are giving false positives:
The following PSScriptAnalyzer rule 'PSDSCUseIdenticalMandatoryParametersForDSC' errors need to be fixed:
MSFT_SPSearchContentSource.psm1 (Line 1): The 'Required' parameter 'ScheduleType' is not present in 'Get-TargetResource' DSC resource function(s).
MSFT_SPSearchContentSource.psm1 (Line 219): The 'Required' parameter 'ScheduleType' is not present in 'Set-TargetResource' DSC resource function(s).
MSFT_SPSearchContentSource.psm1 (Line 683): The 'Required' parameter 'ScheduleType' is not present in 'Test-TargetResource' DSC resource function(s).

The specified parameter however are parameters in subclasses, which should not be present in the *-TargetResource methods.

The specified parameter 'ScheduleType' exists in the class MSFT_SPSearchCrawlSchedule, not in MSFT_SPSearchContentSource which is implemented in the psm1 files:

[ClassVersion("1.0.0")]

Suggested solution to the issue

Roll-back to the previous version or have the issue fixed in PSSA.

I have already created an issue in the PSSA repo: PowerShell/PSScriptAnalyzer#1192
