Theia terminal extension must propagate error from che-machine-exec

Describe the bug

After something went wrong with my workspace (f?url=https://github.com/eclipse/che-dashboard) I got Theia with empty tabs for tasks and terminal. Refreshing a page does not help. Empty tabs make impression that terminal/tasks are loading but actually they failed, if I check websocket connections I have the following errors:

Che version

• latest
• nightly
• other: please specify

Steps to reproduce

It can’t be reproduced stable but I got it after.

1. Create che-dashboard workspace: f?url=https://github.com/eclipse/che-dashboard
2. Start a terminal
3. Start Install Dependencies task and wait until it’s finished.
4. Start Build task. Actual behavior: Build task is empty forever, it’s not possible to use already initialized terminal.

Expected behavior

The progress of Build task is shown. It’s possible to use already initialized terminal. Or at least theia propagates errors which happens during communication with che-machine-exec via websockets.
