docs(buglog): record bug-1503 — scheduler-before-worker join leaves slots unknown

Browse source 
Job PEND root cause when the scheduler registered before the worker:
xcesched_push_workers only fires on scheduler join (sched.c on_scheduler_join),
so a later worker join's slots (set_host_slots from hconfig->mxj=8) is never
re-pushed to the scheduler -> allocation unsatisfied (slots total 0) -> PEND.
Operational fix (no code change): start controller -> worker -> scheduler so
the scheduler's join-time schedworkers push carries the worker's slots.
