code coverage calculation: treat switch case statements correctly

[johannes-mathes]

Bug description

If I have a switch/case statement with falling through, the coverage is not calculated correctly

Steps to reproduce

Define a switch case statement with falling through (intentionallly):

switch (chargingType) {
                case EnumStatusChargingTypeActiveEnum.Type1:
                case EnumStatusChargingTypeActiveEnum.Type2: {
                    this.currentChargingType = ChargingType.A
                    break
                }

write a test case calling the code either within a for loop or even with mentioning Type1 and Type2

Type1 is not marked as covered

Desired behavior

Type1 should be marked as covered, as there is a test for it
