[PATCH 7/8] alfred: vis: fix jsondoc output for nodes without vis entries

[Sven Eckelmann <sven@narfation.org>]

vis_read_answer() skipped the entries handler when a received vis record
contained no entries. For the jsondoc format, the per-node object is opened
by vis_jsondoc_interfaces() but only closed at the end of
vis_jsondoc_entries().

The entries handler must always be called and all entry handlers must
handled `entries_n == 0`.

Fixes: 38eae4d50e81 ("vis: Add an output format which is json conformant.")
