Pass response as str to bsoup for "my ip" card

Due to how the response is now reformed into a new bsoup object when
bolding search query terms, creating an ip card for "my ip" searches
threw an error due to how the new bsoup object was initialized for the
"my ip" card. This passes the response in as a string instead.

Fixes #504
