Unhiding an object using LocationService API does not update visibility in search results.

STEPS TO REPRODUCE

1. Create an object 'Test Article'
2. Hide the object.
3. Notice that the object is no longer returned from eZSolr.
4. Unhide the object using LocationService Api.
5. Notice that the object still is not returned from solr.

Note:

There seems to be a typo in eZ/Bundle/EzPublishLegacyBundle/Resources/config/slot.yml

Please check lines 92-96

    ezpublish_legacy.signalslot.unhide_location:
        class: %ezpublish_legacy.signalslot.unhide_location.class%
        arguments: [@ezpublish_legacy.kernel]
        tags:
            - { name: ezpublish.api.slot, signal: LocationService\UpdateLocationSignal }

It seems that the correct line should be:

            - { name: ezpublish.api.slot, signal: LocationService\UnhideLocationSignal }
