BOINC doesn't resume after inactivity period

[pezcurrel]

Describe the bug
BOINC doesn't resume after inactivity period.
It's not an idle time detection problem, beacause with "idle_detection_debug" activated in "Event log options" I get log messages like

Steps To Reproduce

1. run boinc
2. run boincmgr
3. set "'In use' means mouse/keyboard input in last [x] minutes" to 1 in preferences and save
4. wait 1 minute without touching mouse and keyboard: tasks won't resume (they will still show a "Suspended - computer is in use" status)

Expected behavior
BOINC tasks should resume after the inactivity period
