test-run does not work when placed inside a test directory

[Totktonada]

The following directory structure:

+ test/
   - my_test_suite/
   - test-run/
   - test-run.py -> test-run/test-run.py

Leads to the following error:

Fatal error: Suite 'cluster-py' doesn't exist. Execution aborted.

While the following works:

+ test
   - my_test_suite/
   - test-run.py -> ../test-run/test-run.py
+ test-run/

Both did work 2-3 years ago.

The error message:

<backtrace>
RuntimeError: Suite 'cluster-py' doesn't exist

Or when -j -1 is passed:

Fatal error: Suite 'cluster-py' doesn't exist. Execution aborted.

The reason is tarantool/tarantool-python@ea9d082.

Workaround:

$ rm test/test-run/lib/tarantool-python/test/cluster-py/suite.ini

find_suite() find test suites recursively, but then pass suite_name as suite_path to TestSuite constructor. It seems, there was idea about arbitrary nesting of test suites, but then it becomes broken.

At least we should exclude everything that is under the test-run directory.
