It is possible that that the |credit_card| has empty year and/or empty month. 
We should fill "month" control type only if the |credit_card| has both year and
month present.

Also, please add unit tests for each case, that is:
 1. year empty, month empty
 2. year empty, month non-empty
 3. year non-empty, month empty
 4. both non-emtpy
