Miscellaneous fixes (0.17 Beta) (#21443)

* Use thread lock for JinaV2 call as it sets multiple internal fields while being called

* fix audio label translation in explore filter

* Show event in all cases, even without non-none match

* improve i18n key fallback when translation files aren't loaded

just display a valid time now instead of "invalid time"
