Including uninitialized, optional, SetOf?

See original GitHub issue

Hi,

After https://github.com/etingof/pyasn1/commit/6fa0e312ea80713983b1a3c1e4529e7452b0e0fe I observe that an uninitialized, and optional, SetOf is being included in the encoded data.

In my case it’s a PrivateKeyInfo structure (https://github.com/etingof/pyasn1-modules/blob/master/pyasn1_modules/rfc5208.py#L49) and before the change the attributes was not being included:

    0:d=0  hl=4 l=1213 cons: SEQUENCE          
    4:d=1  hl=2 l=   1 prim:  INTEGER           :00
    7:d=1  hl=2 l=  13 cons:  SEQUENCE          
    9:d=2  hl=2 l=   9 prim:   OBJECT            :rsaEncryption
   20:d=2  hl=2 l=   0 prim:   NULL              
   22:d=1  hl=4 l=1191 prim:  OCTET STRING      [HEX DUMP]:308204A3...

But after they are:

    0:d=0  hl=4 l=1215 cons: SEQUENCE          
    4:d=1  hl=2 l=   1 prim:  INTEGER           :00
    7:d=1  hl=2 l=  13 cons:  SEQUENCE          
    9:d=2  hl=2 l=   9 prim:   OBJECT            :rsaEncryption
   20:d=2  hl=2 l=   0 prim:   NULL              
   22:d=1  hl=4 l=1191 prim:  OCTET STRING      [HEX DUMP]:308204A...
 1217:d=1  hl=2 l=   0 cons:  cont [ 0 ]

I can get rid of it if I include attributes with an empty attribute, but it seems weird to me that I have to.

Is this how it’s supposed to be? Thanks.
