integTestGen.jl does not use dev branches to determine dependencies

[SimeonEhrig]

During the work on this QEDjl-project/QEDprocesses.jl#19 , I detect an error, because a variable was defined twice: https://gitlab.com/hzdr/qedjl-project/QEDprocesses-jl/-/jobs/5271231765

Normally, this should be captured by the integration tests. But for unknown reasons, QEDbase.jl do not check QEDprocesses. But QEDprocesses has a dependency to QEDbase.jl: https://github.com/QEDjl-project/QEDprocesses.jl/blob/0074aa02285d5ef39e63f5a204e02ac4b5b1f6d8/Project.toml#L8

I found the reason for the bug. The traversing algorithm might be correct. But it uses the states of the Project.toml in the registry. If we a new QED dependency to the Project.toml of a QED project, the new dependency is invisible for the integTestGen.jl until we do a new release in the registry. I will fix it by pull the current dev version, when the integTestGen.jl script is executed.
