Ajustment to load outputs with same Ids saved

[danieldvc]

When some output is removed, the order of outputs affect correct render os connectors when flow is reloaded.

Hi @danieldvc

Thanks for PR.

Can you elaborate more on the problem that it corrects?

For example in node with 3 outputs. Using:

/* 
Node 13  
output_1
output_2
output_3

*/
editor.removeNodeOutput(13,'output_2');

/* 
When using the removeNodeOutput function the numbers are corrected
Node 13  
output_1
output_2 // (output_3 is renamed)

*/

The export always exports in order, is it removing the output in another way?
