tdf#49895: search in Options: check if label exists (related to tdf#157266)

- since ids in ui files can be changed or removed,
we have to check if they are exits or not, to prevent
any crash or misbehavior.
- Proper solution will be iterating over the
widget ids and collecting their strings without
based on a list of identifiers.
