The bug

The frontend doesn't respect virtual directory settings for some API calls.

What I expected to happen

The frontend should respect virtual directory settings for all API calls.

Steps to reproduce

1. Perform a fresh install of Octopus Deploy with a virtual directory (e.g. /Octopus/) configured
2. Open the browser tools and enable network capture
3. Login to the front end interface and remain on the dashboard
4. Note that the first request to '/me' uses the correct virtual directory
5. Note that subsequent requests do not use the correct virtual directory

The same issue is present when using the JIRA connectivity test.
