QtSingleApplication: Fix unreliable '-client' option

Browse Source 
QLockFile documention states:

  When protecting a resource over a long time, however, the
  application should always call setStaleLockTime(0ms) and then
  tryLock() with a short timeout.

Without the 0ms stale lock time the new Qt Creator instance would think
that the lockfile is stale and starts a new instance!
