[xmlsec] xmlsec-mscrypto code review (patch #2)

> I found two copies of the same code one after another: 

Found the reason: the code is actually different. One call is "adopt 
cert" and
another is "adopt key cert". Both are required. Resurected the delete 
call in both
places: keysstore.c and app.c (see the review for "MScrypto IS patch" 
from Wouter).


Mea culpa,

Aleksey
