[PFW] Fix issue when setting a parameter of a configuration not applicable

BZ: 93374

This patch aims to fix an issue when using the command setConfigurationParameter
to update the value of a parameter of a configuration.
The autosync shall be turned off when updating the value of a parameter in a
configuration that is not currently applicable.
