firstModule calculation is wrong

[Leo1212]

Describe the bug
I started in H21 but have some modules with a start date bevor that (TA.MAREP.2102, I.BA_INFO_ABEND_RK.H2001, I.EN_PFLICHT_NEIN.AIML) these modules should be ignored.
But in the statistic my modules are shown as Semester 3.

Expected behavior
The statistic should start at Semester 1.

Actual behavior
The statistic starts at Semester 3. Ignoring the modules does not help.

Steps to Reproduce

1. Add the modules (removed personal data):

I found out that only the module I.BA_INFO_ABEND_RK.H2001 is responsible for the wrong calculation.

I've fixed the issue for me locally but haven't yet gotten to pushing it. Here's the sauce if anybody wants to fix it for themselves.
