test: move unit/ to test/

This virtually reverts commit 436218d
('move unit tests to unit'), that was made in the scope of #106.

Despite the fact that testing of the connector uses `unittest`
framework, it is functional (and integration) testing by its nature:
most of the test cases verify that public API of the connector properly
works with tarantool.

In seems meaningful to locate such kind of test cases in the `test/`
directory, not `unit/`, disregarding of used framework.

Follows up #106.
