test: disable persistent connection testing

tarantool-3.ini configuration fails and it seems the reason is gh-113
('Receiving trash from persistent connect when there was timeout
before'). Disabled both tarantool-2.ini and tarantool-3.ini
configurations, where persistent connections are used, until the problem
will be resolved.

Related to #113.
