Add missing test to WeakPtr

I discovered we have a weak pointer now and in my quest to understand how it works
I spotted case that was not tested:

1) ctor weakptr a
2) ctor factory f
3) ctor weakptr b
4) dtor weakptr b
5) dtor factory f
6) test a

Mostly because I thought I saw a mistake but alas it works as-is but still
the test is missing.

BUG=none
TEST= this is a test
