1. resultLanding.service.ts: [Bug fix] Spelling error in parsing of "eoscifguidelines" field.
2. showSubjects.component.ts: [Bug fix] Do not show "EOSC" label in classified subjects, when no "eoscSubjects" parsed.
3. searchFields.ts: In RESULT_ADVANCED_FIELDS added "eoscifguidelines" | Added method "getResultAdvancedFields()", which does not include "eoscifguidelines" in "RESULT_ADVANCED_FIELDS" when environment == "production".
4. searchAll.component.ts & searchResearchResults.component.ts: Get searchFields.RESULT_ADVANCED_FIELDS from "getResultAdvancedFields()".
