Go to declaration always shows 2 files, relative and absolute paths

Type: LanguageService

Describe the bug

• OS and Version: Ubuntu 14.04.5
• VS Code Version: 1.24.1
• C/C++ Extension Version:
• Other extensions you installed (and if the issue persists after disabling them): yes
• A clear and concise description of what the bug is.

The issue is that my workspace folders setting contains only the current dir "." and ctrl+p
open file using the relative path, BUT, the problems tab show the problems in the same file
but with the absolute path and when I click on a problem, it opens the same file twice.
1 with relative and 1 with absolute path.
It also happens with "goto declaration", it shows 2 files, 1 with relative, and with absolute path.
Is there a way to use only relative or absolute path?

Steps to Reproduce:

1. Open file using ctrl+p
2. Click on the of the problems in that file from the problems tab

Expected behavior

If the file already open, it should navigate from the problems tab to the open file
