Merged requested to merge chleh/ogs:fix-ip-data-getter into master
I accidentally messed up the IP data output of Kelvin vectors earlier this year (!4222 (merged)). At least the small deformation and hydromechanics processes are affected.
This MR fixes that issue and adds some unit tests for the IP data getters and setters.
