FileStateFactory creates a non empty FileState on creating a new agent.

[svenstm]

I created two agents right after each other. When trying to set the xmpp account I complains it already has a username and password:

Compare:'merlin'/'merlin' to 'henk'/'askask'

I tried tracing when it goes wrong, but it happens somewhere where the file is created for the agent. FileStateFactory:98

Found the issue: in both the old and the new version of FileState there was in incorrectly "static" structure, which provided a small, but very real race-condition. Moreover, it was always triggered if an empty statefile was opened.

It's currently fixed in the Master, probably I'll backport a hotfix to the 1.0.x series.
