Description of problem:
Clicking on column headers of webtrans cause the editor view to be opened with the most recent document that was open. The click also sorts by that column, but this is not visible until returning to the document list.

Version-Release number of selected component (if applicable):
1.4 commit d926af1e98870d0d82ca and earlier

How reproducible:
Always

Steps to Reproduce:
Already fixed in commit 256fe12a8eaa3aca3655
1. Build from commit d926af1e98870d0d82ca
2. Open webtrans with any project version
3. Click a document to open the editor
4. Click project name to return to doc list
5. Click a column header label

Note: I forgot to try clicking a column header before loading any document.
  
Actual results:
Doc list is hidden and editor is shown with previously selected document.
Doclist is sorted by the clicked column.

Expected results:
Doclist stays visible.
Doclist is sorted by the clicked column.
