V7b1: Nbconvert jumps to the wrong link in collaboration mode

[SaturnTsen]

Describe the bug
Nbconvert jumps to the wrong link in collaboration mode.

To Reproduce

1. Install and activate jupyter-collaboration
2. Open any .ipynb file
3. File - Save and Export Notebook As - LaTeX (or other options)
4. The server returns 404, because the the browser goes to /nbconvert/latex/RTC%3AFILENAME.ipynb?download=true instead of /nbconvert/latex/FILENAME.ipynb?download=true

Expected behavior
the browser goes to /nbconvert/latex/FILENAME.ipynb?download=true
