> This occurs when status command response is received after start of next stage which
modifies sch state (quite often on starting services during install).
> # status command is sent to agent (happens every 60 seconds)
> # start commands are scheduled, generated event which move sch from INSTALLED to STARTING
> # status command response received from agent. sch status directly set to INSTALLED bypassing
state machine
> # All subsequent task reports from agent trigger InvalidTransitionException, as OP_INPROGRESS
event tries to do STARTING -> STARTING transition.
> # However at task end we support INSTALLED -> STARTED transition for STARTED event.
So tasks finish normally.
