Combined Report to include test runs from the child folders

[tikolakin]

Is your feature request related to a problem? Please describe.
Combined report doesn't include test runs that are in a nested folders.

Describe the solution you'd like
Combined report should include test runs from the child folders

Describe alternatives you've considered
Currently the only way to see a combined report is to expand all folders and select test runs for a combined reports.
Yet checkboxes are available only on the main runs page view. Which is too many repeatable clicks

Additional context
By implementing it I can significantly reduce time to gather report. 1 click vs 2 mins clicks.
This is a quite frustrating on busy days ..

• how many nested folders do you have in root folder?
• how how many runs in nested folders?
• how deep is your nested structure in runs?
• when you're going to use combined report how many runs do you compare?
• what is you have hundreds of runs for combined report? I don't think it will be usable

@littlefrontender do we need backend support to get all runs from nested folders to get to combined reports?

1. we have 3 levels, but 2 levels is enough, like parent -> parent -> child -> test run. We are interested in "parent -> child -> test run" bit
2. it depends, from 1 to 1 hundred. But the current use case is each child has from 1 to 5 test runs. And we have ~ child folders. So 10-25 test runs in question
3. 3 levels max, there are some exceptions. But 3 is manageable enough
4. 10-25
5. Exactly, we are not interested in hundreds of test runs, that's why we opt into folders.
