Require 'embedding date' in 'Register paraffin blocks' wizard
The wizard currently allows the registration to proceed without an 'Embedding date'. This creates a big problem for the 'Lab tracking protocol for FFPE/HE' since the Histology samples that was on the original work list are selected again for the next list to create (due to the missing date).
This situation is fortunately spotted since when printing the new list all samples are listed as already located on existing paraffin blocks (eg. PB00122 A1).
