RFR: 8274433: All Cells: misbehavior of startEdit

The misbehavior happens if (super) startEdit didn't succeed (== !cell.isEditing):

- must not fire editStart event
- must not update control's editing location

fix is to back out of startEdit if super.startEdit doesn't switch the cell into editing mode

Added tests that failed/passed before/after the fix. Note that for Tree-, Table-, TreeTableCell one of the added tests would be a false green due to those cells not updating the editing location on its control [JDK-8187474](https://bugs.openjdk.java.net/browse/JDK-8187474), so it's ignore until that's fixed.
