Fix race condition in SqlTask createTaskInfo

This fixes a race condition in the task info management of SqlTask.  When a
SqlTask finishes the TaskInfo is stored permanently, and all calls to getTaskInfo
return the final instance.  The problem is while the final task info is being
updated another thread may create a new task info with a higher version number
in the running state.  The client will receive the higher version number and
reject the final task info with a lower version number.  The query will never
finish because it the final task info version number never increases.

The fix changes the SqlTask to always return a new TaskInfo for each call to
getTaskInfo with a new version number.
