Dependency-Track BASE_PATH removed in projects

### Current Behavior

After fixing issue #1288, which duplicated BASE_PATH, when opening a project in a new tab, the BASE_PATH is removed, resulting in a 404 Not Found error.

### Steps to Reproduce

1. Open Projects tab.
2. Right-click on a project > Open link in a new tab.
3. It throws a 404 Not Found. The new tab does not reflect the BASE_PATH. E.g.: instead of opening http://localhost:8080/base_path/projects/, it opens http://localhost:8080/projects/

### Expected Behavior

1. Open Projects tab.
2. Right-click on a project > Open link in a new tab.
3. The new tab opens the project correctly with the BASE_PATH.

Reproduce the issue from the Projects tab using the right-click/open-in-new-tab steps, then trace how the project link is generated and how BASE_PATH is handled. Done means opening a project in a new tab retains BASE_PATH and no longer returns a 404.
