daemon: fix memleaks in GetStatistics and GetHistory

Browse source 
dbus_g_method_return[_error] does not claim the passed parameters, the
caller must free it theirselves.

complex is filled with an GValueArray pointer (see
UP_DBUS_STRUCT_DOUBLE_DOUBLE) but its contents are not freed (memleak!).
This patch introduces a deprecation warning due to the use
g_value_array_free, but since UP_DBUS_STRUCT_DOUBLE_DOUBLE is a
GValueArray, this is unavoidable.
