Debug report-last 20 logs entries & screenshot procedure

**Describe the bug**
1. Clicking on the last 20 log entry blue button does not display the last 20 log entries. Clicking on +last
20 log entries does.
2.Consider removing the text in the screenshot menu "RIGHT CLICK IN IMAGE PREVIEW -> COPY". Right clicking doesn't display anything; clicking on +screenshot produces the image.

**To Reproduce**
Steps to reproduce the behavior:
1. Click on Report modal
2. Click on the blue button for +last 20 log entries; see error
3. Click on +last 20 log entries; see list of entries
4. Click on the mini screenshot; see error
5. Right click on the mini screenshot; see error
6. Click on +screenshot; see enlarged screenshot

**Expected behavior**
Simplified debug error capture procedure

**Desktop (please complete the following information):**
- OS: Windows 8.1
- Browser Opera
- Version: 2.0.181129
- Version: 2.0.181121-rc1
- Version: 2.0.181121-rc2

Start at the Report modal and reproduce both the last-20-logs button behavior and the screenshot instructions using the described steps. Inspect the frontend entry points for these controls, then verify that the blue button displays the entries and that the screenshot procedure no longer presents misleading right-click guidance.
