[Defense Elvis] Make sure sidebar doesn't break if there are any missing values in the payload

[nightsh]

In the API payload used to populate the sidebar, we might miss a few values in the case of Defense Elvis manual data.

The task here is to make sure missing data:

• doesn't break the layout
• doesn't crash the Ember components
• doesn't throw any exceptions

If everything works fine, then we can mark this as done. Otherwise, we need to fix values handling within sidebar components.

In node details response manual data is missing the following fields:

• For Bid: TEDCANID, isSubcontracted
• For Lot: description, awardDecisionDate, selectionMethod, estimatedValue
• For Tender: TEDCNID, description, isEUFunded, isCoveredByGpa, isFrameworkAgreement, procedureType, isDirective
• For Bidder/Buyer: country

Just beaware that we are going to remove the Tender Details page as part of #505 so there is need to spend effort on the Tender Details template.
