Thanks for the changes.

The code also moves the cert into the beginning of the array. Here's the 
scenario I was asking, suppose the cert chain is:

   c0 c1 c2 c3 c4

Suppose c4 is the cert being requested. The code will generate this 
result without any problem:

   c4 c0 c1 c2 c3

However, suppose the requested cert is c2. The code will move c2 to 
first and shift the rest back by one position:

   c2 c0 c1 null c3

c4 can't be moved into the result since there isn't enough space.

If the scenario is possible, the code would include a null in the result 
and possibly generate an index-out-of-bound error when moving c4.

If the scenario is not possible, the code could be optimized to check 
the requested cert only against the last cert in the CA chain.
