Description of problem:
This is a follow up to bug # 1305057
After creating new managed repository in Administration perspective with option "Automatically Configure Branches" enabled, the branches dev & release are created, but they are not initially listed in the dropdown for switching the branches.

Attached video with steps to reproduce (this video is recorded using 6.2.2 patch, but the issue is the same in 6.3.0.DR2). The issue is visible in 0:22 after repo is created - only master branch is shown. I need to leave perspective - return to perspective to actually see other branches there.

Version-Release number of selected component (if applicable):
BPM Suite 6.3.0 DR2

How reproducible:
Always

Steps to Reproduce:
1. Login with user who has role kiemgmt (needed to be able to create managed repository)
2. Go to Administration persp., Repositories > New Repository
3. Fill in name and check "manage repository", click next and make sure Automatically configure branches (master/dev/release) is selected and click Finish
4. Check the main panel on the right (Repository edito) contains the newly created repo

Actual results:
The dropdown for selecting branches only contains "master" option.
But when I navigate to different perspective (e.g. authoring) and then get back to Administration, then the select contains all the branches (master/dev/release)

Expected results:
The dropdown in Administration > Repository Editor should contain all the branches after Managed repo is created with "Automatically configure branches" option.
