Stopping of inactive workspaces by timeout doesn't work in Eclipse Che

[dmytro-ndp]

Reproduction Steps

There are two Eclipse Che properties:

• CHE_WORKSPACE_AGENT_DEV_INACTIVE__STOP__TIMEOUT__MS;
• CHE_LIMITS_WORKSPACE_IDLE_TIMEOUT.

Setting them to non-zero values don't lead to stopping idle workspaces by timeout set by these variables.
Possible reason is that WorkspaceActivityNotifier is calling WorkspaceActivityService by schedule and it makes idle (inactive) workspace kind active.

OS and version:
Tested on Multiuser Eclipse Che ver. 6.0.0-M5-SNAPSHOT, docker infrastructure
