Link to 'View all branches' on a branche's stage give a 'Page not found' error

Summary

When a plan has a branch (not only master) and more than one stage, after selecting the job results from one of the stages, two problems happen:

1. The Plan vanishes in the top path
2. The View all branches link leads to a Page no found page when you're not on the master branch

Steps to Reproduce

1. Have a plan with at least one branch enabled
2. Add a second stage with valid jobs on both stages
3. Successfully run this plan on both master and branch
4. On the Build result screen for the branch select the job in one of the stages (see screenshots for details)

Expected Results

The plan should appear on the top path and the View all branches link should take us to the plan's branches.

Actual Results

The plan isn't displayed in the top path (see screenshots) and the View all branches link takes us to a Page not found page.

Notes

When the Build result screen is selected, the (working) View all branches link is like https://<instance>.atlassian.net/builds/browse/<PROJECT-ID>-<PLAN-ID>/branches
However, when the Job result screen is selected (after clicking one of the stage's jobs) the link to the View all branches is https://<instance>.atlassian.net/builds/browse/<PROJECT-ID>-<PLAN-ID><BRANCH-ID>-<BUILD-ID>/branches which leads to a Page not found page.
