Fixed skipping TSL validation when LOTL has changed but validation is turned off
Created by: rvillido
This change fixes a small bug that was introduced in DSS-883 (revalidating TSLs).
The problem is that when TSL signature check is turned off (checkTSLSignatures=false), then it still validates TSL, but sometimes we don't want to validate TSL (in some test cases).
This is fixed in the branch 4.7.x
