Make backend more robust, to prevent 'stuck' workunits. Now 

transitioner will not sent the transition_time to INT_MAX
UNLESS a canonical result has been found.  Otherwise it is
set to MAX(ten days, 1.5*delay_bound) in the future.  This
ensures that the transition will 'see' the workunit again
if no canonical result has been found.
