Revised PauseAtHeight.py. The changes are:

Browse source 
For non-Repetier and non-Ultimaker printers - Move the prime extrusion so it occurs while the print head is still in the parked position so the blob doesn't happen over the print (GitHub #13584 and #11471 for reference).

Add a user option to use M104 or M109 for the resume temperature to avoid an unnecessary delay if the resume temperature is the same as the standby temperature.
