ovsdb-cs: Consider default conditions implicitly acked.

When initializing a monitor table the default monitor condition is
[True] which matches the behavior of the server (to send all rows of
that table).  There's no need to include this default condition in the
initial monitor request so we can consider it implicitly acked by the
server.

This fixes the incorrect (one too large) expected condition sequence
number reported by ovsdb_idl_set_condition() when application is
trying to set a [True] condition for a new table.
