Make _exportType and _triggerDownload properties protected

[Stern87]

Prerequisites

• [x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [x] The issue still exists against the latest master branch of yii2-export.
• [x] This is not an usage question. I confirm having gone through and read the documentation and demos.
• [x] This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• [ ] I have attempted to find the simplest possible steps to reproduce the issue.

Steps to reproduce the issue

1. Create class that extends 'kartik\export\ExportMenu' class
2. Write 'run' function in order to override parent function
3. Try to access $this->_exportType and $this->_triggerDownload properties

Expected behavior and actual behavior

When I follow those steps, I see that I can't access those properties since they are private.

I was expecting that they will be protected as all others.
