test: test OP_CSV empty stack fail in feature_csv_activation.py

With BIP112 activated, the operation OP_CHECKSEQUENCEVERIFY (former OP_NOP3)
leads to script interpreter termination with an error if one of the following
conditions is true:
    -> stack is empty
    -> top item on stack is negative (< 0)
    -> top item on stack has disable flag unset and at least one of
       four other conditions is true (contains the core CSV logic)

This commits adds the missing empty stack failure test to the functional test
by prepending a valid scriptSig with just OP_CHECKSEQUENCEVERIFY. If BIP112 is
inactive, the operator just behaves as a NOP (for both tx versions 1 and 2) and
the transaction remains valid -- if it is active, the tx is invalid due to an
empty stack (for both tx versions 1 and 2, as well).
