Title: Prevent exception when publicProfileUrl isn't set

I don't think publicProfileUrl is set unless you've specifically configured it in your LinkedIn profile.

This should prevent oneauth from barfing:

```
Unhandled Exception

Message:

Undefined index: publicProfileUrl

Location:

.../bundles/oneauth/libraries/oauth/provider/linkedin.php on line 59
```
