[BUG] Link to Epic Broken from a different project's Kanban Board

[cerealkella]

When clicking on an Epic from within a project where the Epic did not originate, the link is incorrect and goes to a 404.

Describe the bug I am in the Project_2 Kanban and the Epic was created in Project_1. Clicking on the Epic link above the User Story will take me to: {base_url}/project/project-2/epic/id - which is incorrect. It should be {base_url}/project/project-1/epic/id

How can we reproduce the behavior create 2 projects and an epic and try to click on the epic in the kanban from the project the epic was not created in. on the board only, when you go into the User Story it works as expected.

Workarounds Open User Story and click on Epic from there.
