pulsekit/dev: Fix for recorded TestPersonalOK test

Because of synchronization request/response, which got recorded altogether with xmlrpc communication, the `TestPesonalOK` test fails with:

```
--- FAIL: TestPersonalOK (6.80 seconds)
        dev_test.go:35: expected err to be nil, was "java.lang.NullPointerException\n" instead (i=0)
        dev_test.go:38: expected i to be greater than 0, was 0 instead (i=0)
```
