Observed behavior is that Bamboo is performing export (for example scheduled export) and after some time later Bamboo pauses itself.

Steps to reproduce:
0) have empty Bamboo instance (no running plans, etc)
1) create a plan with a script task "sleep 10d"
2) run that plan - it will run infinitely
3) administration->export->run export, wait for it to finish (Bamboo for a while will be in PAUSING state)
4) bamboo will get back to RUNNING state
5) stop your running plan
6a) bamboo becomes "PAUSED"
6b) while we would expect no pause would occur
