[PATCH] tests: Avoid printing the entire test database

[Valters Jansons <valter.jansons@gmail.com>]

Lua tests currently iterate the database, and dump all of its contents
into the runner's log. This might be beneficial in testing, however it
does not necessarily help during regular builds.

This commit retains the reverse_pointer() invocation, but instead of
printing simply counts the number of entries and asserts at at least
something existed.
