Facets - aggLang variable it's not always replaced properly producing different results in the search filters

[josegar74]

Describe the bug

When configuring a facet with aggLang variable

  "OrgForResource": {
    "terms": {
      "field": "OrgForResourceObject.${aggLang}",
      "include": ".*",
      "size": 20
    },
    "meta": {
      "caseInsensitiveInclude": true
    }
  },

This code calculates the value to replace in aggLanguage

https://github.com/geonetwork/core-geonetwork/blob/16df8661ea18dfbe36e976bc5f7bdbe4ac829e44/web-ui/src/main/resources/catalog/components/elasticsearch/EsService.js#L47-L93

Sometimes the parameter state only contains a property filter and others contains additional properties like languageStrategy that causes different output.

To Reproduce Steps to reproduce the behavior:

1. Go to https://apps.titellus.net/geonetwork/srv/dut/catalog.search#/home (Dutch UI) and select from the menu the search option Zoeken --> The Organisation facet is displayed

The search request request the aggregation field OrgForResourceObject.default

2. In other tab open the search page in Dutch --> https://apps.titellus.net/geonetwork/srv/dut/catalog.search#/search --> The organisation facet is not displayed

The search request request the aggregation field OrgForResourceObject.langdut

Expected behavior Results are the same.

---

This code probably should be initialised with the settings values for languageStrategy and other fields:

It's unclear in case 1. how is filled, as the code that seems to fill that object it's not executed:

https://github.com/geonetwork/core-geonetwork/blob/16df8661ea18dfbe36e976bc5f7bdbe4ac829e44/web-ui/src/main/resources/catalog/components/search/searchmanager/SearchFormDirective.js#L372-L380

@fxprunayre any idea about this?
