Some tests fix

1. form [Check docs](http://check.sourceforge.net/doc/check_html/check_4.html#Test-Timeouts)
  > all tests are run with a timeout, the default being 4 seconds. If the test is not finished within that time, it is killed and logged as an error.
  
  I've removed this functionality to make it possible to run tests on slow mashines
2. fixed wrong condition in getself_name() test
