fix: Make sure the correct record is selected after an execution

[mhan83]

Description

Select the correct test record in the tree after a test run completes.

Using the TreeView's reveal api requires the data provider to implement the optional getParent method. The implementation I added is going to look a little strange since I couldn't find an explicit reference from a TestStep to its parent TestRecord. The implementation uses img_url as the way to map them since img_url contains the jobID in the path. We're not actually using the reveal api to currently select TestSteps though, only TestRecords. So the implementation in this PR is technically not necessary. The alternative is to just return null which signals to the TreeView the item being revealed is a child of the root (i.e. TestRecord). Both not ideal! So I'm open to whichever one the team thinks is less confusing.

@mhan83 Do you think its worthwhile to keep the test steps in the history view? If not, then we can remove it here and that'll also conveniently remove the need to work out the test step vs test record mapping 🤔

If the test steps are removed, I think we'd want to migrate away from a TreeView. The TreeView will always show the chevron even if there are no children to render:

Actually it was pretty straightforward to remove the children from the history view.
