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

**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?

Start in web-ui/src/main/resources/catalog/components/elasticsearch/EsService.js at the aggLang replacement logic, then trace the state initialization and update paths in searchmanager/SearchFormDirective.js. Reproduce the two Dutch search-page flows and compare their aggregation requests. Done means both flows produce the same expected aggregation field and facet results.
