fix: Incorrect sum of rest jobs printing time

[mdziekon]

Description

This PR fixes a bug in the Jobs queue, where the "rest of jobs" does not correctly sum up estimated printing time of the rest files. Instead of summing up all of the rest jobs, it takes into account only the last element of the list.

Bug is caused by a simple omission of addition operator in code.

Steps to reproduce

1. Place 5 random models into the Queue
   • (so that the next item in the queue will not be displayed directly)
2. Add two more DISTINCT models with different estimated times
   1. One with estimated print time of eg. 5h
   2. One with estimated print time of eg. 1h

Expected behavior

• Summed up estimation displays "6h of print time"

Actual behavior

• Summed up estimation displays "1h of print time"

Notes

• Bug does not occur when adding the same model multiple times, that is, when combinedIds internal feature is being used.
