Why do you return a table with boolean, but not boolean?

It is better to use output filtering feature of test-run to avoid such
redundant diffs.
Consider test/app/socket.test.lua:
```
12 env = require('test_run')
13 test_run = env.new()
14 test_run:cmd("push filter '(error: .builtin/.*[.]lua):[0-9]+' to '\\1'")
```
It is not a blocker for that patch, but if you intend to include it, do
it in the separate commit before 'add a method to check if txn is open'.
