macOS: Extend accessibility testing of treeview

Browse Source 
Check that we can navigate to rows and columns, and that we get the
right text back for cells.

We see API failures in CI on some macOS nodes, accompanies by the debug
message:

AXUIElementCopyAttributeValue( "AXTitle" ) returned error =
  AXError(value=-25201, name=kAXErrorIllegalArgument,
  description="An illegal argument was passed to the function.")

On hosts where the test fails, we always see this warning, so extend the
test helper with an errorOccurred boolean that we can test and if set
skip the test.
