Do not update RM config with previous sequence

If an application info update is pending and
RM#applyConfigurationToResourcesLocked is called with a config
with an older sequence that RM's current global config, the application
info update should not be applied, nor should the global config be
updated with the older config.

Similarly, when an application is updated and there is a pending
application info change for the previous version of the package,
clear the currently pending application info updates for that package
to prevent the old overlays from being applied on top of the newly
updated application.
