Configuration deploy erroneously restores outdated setting versions.

[svenoe]

In some rare cases, the sysconfig is erroneously restoring legacy data. This can happen during package installation, but not during Maint::Config::Rebuild, which use slightly different deployment options. After traversing several methods, the problem to my understanding is, that in one case the modified settings which are to be deployed, are gathered via ModifiedSettingListGet (works) or ModifiedSettingVersionListGetLast (can result in errors). The problem here is, that ModifiedSettingVersionListGetLast can contain outdated default settings if the last modification was a reset to default, but the default was changed at some point in time after this reset.

As the SysConfig code is relatively convoluted we will first introduce this change in OTOBO11 and then cherry-pick to OTOBO10 after additional testing.
