makeInteractive Crash fix when NSRange.location == NSNotFound

If the range location can't be found, return without attempting to add a link. This would crash previously.

Thanks!

I do have one question. Why are you using:
guard nsRange.location != NSNotFound else { return self }
Instead of just:
if nsRange.location == NSNotFound { return self }

Mainly just personal preference. To me, it reads better. If I use an “if” statement, I typically expect the body to do something. The guard is then just used more as an assert. Both accomplish the same thing in this case.
