#130 capsinfo before and after an injection look too different for the MAWI dataset

The capture duration specifically is enlarged by injecting attacks. Issue seems to sit [here](https://git.tk.informatik.tu-darmstadt.de/SPIN/ID2T-toolkit/src/master/code/ID2TLib/Utility.py#L62).

Capture duration should be fixed with this commit 69145d59e1e36311e6b7470bcb69ed301dc148c3.
