Temp workaround: Object mode pie glitches since 'Edit Strokes' mode was introduced

To ensure all items of a pie are always at the same position, invisible dummy buttons were added for unavailable items. This caused mainly two issues: Command line printed warning because of the > 8 elements, and some modes weren't visible in some cases ('Object Mode' entry was missing in stroke edit mode).
To solve this nicely, we had to support > 8 items per pie. Will look into that this week, but for now, drawing dummy buttons is disabled.

From a user POV this has two ugly consequences: 1. While this temporary workaround is used, *some* pie items are positioned differently than before, 2. The 'Edit Strokes' mode entry might change its position depending on the amount of available modes.
