Support specifying locale in filter & order fields after locales are renamed
This release fixes an issue where query parameter filters that included a locale part (such as fields.myLocalizedField.de-DE=Hallo) would no longer work if the locale they referred to was renamed from a different locale code. The same issue applied to order parameters that specified a locale. E.g. if you wanted to order entries by a locale other than the one specified in the locale query parameter.
