Issue

Dynamic block is displayed on the page even when the related catalog price rule condition is not satisfied.

Steps to reproduce:

1. Create two products.
2. Create a catalog price rule applicable only for one of these products.
3. Create a dynamic block and assign the newly created catalog price rule to it.  
4. Create a widget with the following parameters:
   • Type = Dynamic Block Rotator
   • Dynamic Blocks to Display = Specified Dynamic Blocks
   • Specify Dynamic Blocks = block form step #3
     Layout Updates (can be any)
   • Display on = All Product Types
   • Container = Product auxiliary info
5. Perform reindex and flush cache.
6. Check both product pages for dynamic block form step #3

Expected result:
Dynamic block appears on the first product page only.

Actual result:
Dynamic block appears on both product pages.
With Dynamic Blocks to Display = Catalog Price Rule Related on step #3 the result is the same.
