Issue with dependencies not being set

[YHordijk]

I found an issue where dependencies are supposed to be set by the workflow, but they are not used when submitting it.

The issue seemed to be that in the dependency method we were using the conditional
if otherjob.can_skip, but it is a method and not a property so it always is True. Further, this would not work if the job is currently being managed by Slurm, as then can_skip always returns True, even if it is currently running or pending. We needed to add a new method called in_queue, which checks if the job is being managed by slurm
