Slipping free mistakenly refers to soulbinding, and other messages to clear up

When you slip free from an idle owner while soulbound, it says "Your past owner has lost the last of their own humanity, shattering the soulbinding between you." Even when your previous owner is still animate.

Seems I didn't fix this in !1100 (merged).

If it's just a text clear-up, there might be a few more tidies people have reported to fix at the same time:

• No 'no items to return' message from soulbinder (fetch e.g. pet when have pet - https://discord.com/channels/169683982793965569/450832513401749505/920052024211542026, #579)
• Struggle percentage too prominent in message to owner (and items remain confused by it - https://discord.com/channels/169683982793965569/450832513401749505/918115130296897567)
• Struggle percentages can be confusing when moving between dungeon and overworld, especially when negative - https://discord.com/channels/169683982793965569/450832513401749505/922998643588464732
• Message to owner about item consenting to be soulbound may lead the owner to believe their item has locked, which isn't necessarily the case -https://discord.com/channels/169683982793965569/450832513401749505/914017928758841344, https://discord.com/channels/169683982793965569/450832513401749505/915981441060470854
