Fix #6860 DIR crash when VF are started from the scheduler

- the 2016 feature "to implement MaxVirtualFullInterval" from the
  COMMUNITY add a field to the "class RUN" but forget to initialize it
  to NULL in RUN::clearall() and then got 0x5555555555555555 instead
  this was written in 2016 by Thomas Lohman for the COMMUNITY and
  added in march 2020 for the 12.4.0
- test it with : USE_SCHEDULER=yes REGRESS_DEBUG=1 tests/virtual-backup-test
