Fix UPER encoding of empty SEQUENCE OF 

A length determinant was not added when the SEQUENCE OF was empty
according to the X.691 #20.6 and #11.9.4.1.

This fixes a failure in 16-SEQUENCE-bundle

Decoding 1 bytes of T yielded RC_WMORE after byte 0
Original random structure:
T ::= {
    list: list ::= {
    }
    guard: 01
}
