bump test-run version

[ligurio]

commit 4aaadb9261b7d176f28bb2f1217b296268126762 ('Fix luacheck warnings') fixes luacheck warnings in Lua source code. Bumping version allows to remove test-run directory from exclusions in .luacheckrc in tarantool repository.

I'll bring a few context details:

1. There are tests in the unit directory, which is run by python setup.py test and in CI.
2. There are tests in the test directory (added within PR #109), which is run by cd test && ./test-run.py and is not run under CI (#111). There is only one test here: cluster-py/multi.test.py.

I had the idea to verify the test-run update and ensure that tests under test-run are working with the new test-run version. However they do not work neither before commit, nor after.

On the current master:

[001] Test.run() received the following error:

On the most recent test-run (72f8b89332b552cf20b2143e6dae7fe5042a9f79):

So, it is broken and will not become more broken. I don't mind updating.
