Title: [eady] Show/hide network activity indicator accordingly

Pretty straight forward. When the authorization web view first appears, it's blank for a few seconds while the LinkedIn auth page loads. This can be confusing to the user. During this time the network activity indicator should be visible and spinning.

The network activity indicator should become invisible upon either a) page load or b) failure to load the page.

This PR fixes the aforementioned issue.
