Ivan Kozlovic 1b2754475b Refactor async client tests
Updated all tests that use "async" clients.
- start the writeLoop (this is in preparation for changes in the
  server that will not do send-in-place for some protocols, such
  as PING, etc..)
- Added missing defers in several tests
- fixed an issue in client.go where test was wrong possibly causing
  a panic.
- Had to skip a test for now since it would fail without server code
  change.

The next step will be ensure that all protocols are sent through
the writeLoop and that the data is properly flushed on close (important
for -ERR for instance).
