[cli 2.16.1] action pdf -> resulting pdf is corrupt in cii invoice having empty DateString

[griesi007]

Visualizing a cii invoice having an empty DateString results in a corrupted pdf. I am seeing a view issues here:

• The pdf should not be created when an exception occurs and the resulting pdf is corrupt
• Also a proper error exit code should be returned. Currently 0 is returned.
• As the invoice successfully validates it would be desirable if the the empty DateString would not lead to an exception and could be handled gracefully
