Fix T85987: Selection when GP is parented

When a GP object was parented to e.g. a bone, box selection as well as
point selection were broken in that the selection from the user would
not correlate with what was actually being selected.

The issue was that box and point selection did not use the active
evaluated stroke data. The fix uses the correct data.
