Direct new employer account login to WPJM dashboard

Steps to replicate:
- Create an employer account by posting a job
- Receive email with notice about account set up
- Go to set your password and log in
- You are then directed here: http://workinoxford.co.uk/wp-admin/profile.php

Could we direct folks to the actual WPJM page first instead of to this profile page?

Reproduce the employer account flow from job posting through password setup and login, noting the current redirect to wp-admin/profile.php. Trace the login redirect entry point and verify that a successful login lands on the actual WPJM page or dashboard instead; done means the profile page is no longer the first destination.
