Fix #3985 - check command should elog

This fixes https://github.com/rapid7/metasploit-framework/issues/3985

## To verify:

You will be testing drupal_views_user_enum that's actually buggy, but no worries, I will fix that one too. It's in a separate issue.

- [ ] Set a fake server: ```ruby -run -e httpd . -p 8181``` in a new terminal
- [ ] Do ```tail -f ~/.msf4/logs/framework.log``` in a new terminal
- [ ] Start msfconsole in a new terminal
- [ ] ```use auxiliary/scanner/http/drupal_views_user_enum```
- [ ] ```set rhosts 192.168.1.64```
- [ ] ```set rport 8181```
- [ ] ```run```
