[2/5] testbot/TestAgent: _SetError() may be called when connecting, that is outside any RPC.

[Francois Gouget]

---

This should fix the following error reporting code error message (from 
job 5610):

Use of uninitialized value in hash element at 
/home/testbot/lib/WineTestBot/TestAgent.pm line 215, <DATA> line 558.

This happens when failing to retrieve agent_version during the initial 
connection (which denotes a flaky network connection).
