Update filmstrip item on metadata update

Due to async metadata loading, when viewing an image progress bar,
after progress completion the main handler hiding progress bar would
also hide filmstrip buttons if in secure mode, but the async metadata
handler was calling a restricted handler that would only update the
controls, not hiding for secure, or updating overflow menu. This
change ensures all UI aspects of the item update are processed upon
metadata loading.
