      Description

      There is a possible race condition in `org.apache.aries.blueprint.compendium.cm.CmPropertyPlaceholder` and `org.apache.aries.blueprint.compendium.cm.ManagedObjectManager`

      There are situations where `ConfigAdmin` service might not be available and returns `null` when queried for the initial `config`.
      In other cases instead, `CmPropertyPlaceholder` receives updates from `ConfigAdmin` thread even before it has completed it's initialization.

      The code doesn't discriminate if `config` is `null` or not, and treats any value as valid, marking `CmPropertyPlaceholder` instance as initialized.

      This leads to spotty errors.

      The suggested fix, that simply prevents that `update(null)` invocation mark the `CmPropertyPlaceholder` instance as initialized, addresses the issue.
