AADRoleEligibilityScheduleRequest fails when assignments exist in both root and AU

[mlhickey]

Description of the issue

Since RoleDefinitionId is shared across scopes, in the case where an object has the role assigned in both scopes the return set is an array and not a single object. This results in failure at
$expirationValue.Add('endDateTime', $schedule.ScheduleInfo.Expiration.EndDateTime.ToString('yyyy-MM-ddThh:mm:ssZ'))

Recommendation is to filter $schedules based on both RoleDefinitionId and DirectoryScopeId:
$schedule = $schedules | Where-Object -FilterScript { $_.RoleDefinitionId -eq $RoleDefinitionId -and $_.DirectoryScopeId -eq "$($DirectoryScopeId)" }
