[SICSR-8439] AC valid check inaccuracy
Product Line:	Cede
Component/s:	Accounting Classification
Affects Version/s:	SICS 4.5.1 SP7
Fix Version/s:	SICS 4.9.5 SICS 4.9.4 SSP1 CHR1
Customer:	Reale Mutua Assicurazioni

Problem:
System can use Accounting Classification without Type of Participation (Method) even when it is mandator

Solution:
When the Accounting Classifications are checked if they are valid or not, and the Type of Participation (Method) is mandatory, make sure the system checks both if the ToP (Method) if it has invalid value and when it is (null). Today it correctly validates the AC if the ToP (Method) is not on the business, but it is missing a validation of the ToP (Method) if this is blank.
