fix(chatwoot): extract content from pollCreationMessage and groupInviteMessage

Two more common person-to-person message types with no content
extractor in getTypeMessage(), so they'd have fallen into the new
generic placeholder instead of showing real content: poll questions
(pollCreationMessage.name) and group invite links (groupInviteMessage
.caption, falling back to .groupName).
