[cuegui] Bug fix missing jobs on MonitorJobs (#1312)

* [cuegui] Bug fix missing jobs on MonitorJobs

When the option group dependent is checked, jobs without dependency are being omitted.

* [cuegui] Bug fix missing jobs on MonitorJobs

- Remove dependent if it has the same name as the job. This avoids missing jobs on MonitorJobs. Remove the parent job is necessary to avoid remove the parent job and all the dependents when del self.__load[j] is called
- Use list comprehension to remove dependent if it has the same name as the job
- List comprehension avoid many nested blocks and follow the project code style

* [cuegui] Bug fix when unmonitor finished jobs with dependents

- AbstractTreeWidget.py > _removeItem(): Check if object ID exists before delete it

* Merge master into fix_missing_jobs_on_monitor_jobs

* [cuegui] Bug fix missing jobs on MonitorJobs
- When the option group dependent is checked, jobs without dependency are omitted.
- Code refactoring
