Unable to use Multiple Extruders on any version higher than 2.7.1

[jgbrown54]

Description of the bug

Simple object with layers 1, 4, 7+ set to Extruder 1, Layers 2, 5 set to Extruder 2, and layers 3, 6 set to Extruder 3. Generated gcode has T0 for Layer1, T1 for Layer 2, and T2 for Layer 3. But layers 4, 5, 6, and 7 do not have any Tx for Tool Change. This works for version 2.7.1 and prior releases but does no work for 2.7.2, 2.7.3, or 2.7.4. Simple object included.`

Sorry ID10T error. I was expecting the T0 or T1 near the beginning of the layer. But it was further down in the gcode.
