Description of changes
Previously, if we didn't find a string as a child of LinkV1 and called .toString(), we ran into an error. This fixes it by simplyfing the code to just return the first child that's a string (if it exists) instead of calling .toString() on the result. We use this to set the a11yLabel if one isn't defined.
Verification
Tested by creating a Link without any children. Verified FURN test app no longer runs into an error.
