[BUG] fix parser crash on unconditional tcp content rules

Since 1.3.17, a config containing one of the following lines would
crash the parser :

    tcp content reject
    tcp content accept

This is because a check is performed on the condition which is not
specified. The obvious fix consists in checkinf for a condition
first.
