StudentQuiz: Implement Fast filter UI redesign

[vuvanhieu143]

Hi @timhunt, this ticket is ready for peer review.

Here’s what I’ve done in this ticket:

• Moved all the filter condition fields into separate groups so we can loop through each group. Conditions within the same group are connected with OR, while conditions in different groups are connected with AND.
• For the state_column_name string: I know it’s not consistent with other strings, but do I need to create a new string for that label?
• Added two new buttons: Mine and Answered.
• Removed some Behat tests using XPath and moved them to filter.feature, I also remove all UI steps. I don’t think we need to test all states like before, but I’d appreciate your opinion. Do you think the current tests are sufficient?

Thanks!
