Bug 16955: Do not clear from cache when adding a new framework

There are several issues with these lines:
1/ $cache is not defined correctly and it not visible inside
duplicate_framework
2/ $frameworkcode is a wrong c/p, it should be $newframeworkcode
3/ these calls are not needed. As we are creating a new framework, the cache
should be empty...

This patch will simply remove these calls

Test plan:
Duplicate a framework and confirm that you do not get any error in your
logs.
