Che: Adaptation for tasks is required

[RomanNikitenko]

The bug is relevant for eclipse/che-theia:next, so for master branch assembly.

Describe the bug

After alignment theia tasks with vs code behavior we need some adaptation on our side.

I still can run che tasks, but at least:

• configure task action is not working
• detected tasks are displayed in different way
• after page refreshing Terminal -> Run Task menu action is triggered only on second click
  Please see the video: https://youtu.be/DXe_R-ubxa8

I tested it on theia side and it works well.
Looks like some changes for task definitions are required on our side.

Che version

• [ ] latest
• [ ] nightly
• [x] other: eclipse/che-theia:next

Steps to reproduce

1. Add to a devfile the section:

- 
    alias: theia-editor
    reference: >-
      https://raw.githubusercontent.com/eclipse/che-plugin-registry/master/v3/plugins/eclipse/che-theia/next/meta.yaml
    type: cheEditor

1. Start a workspace from the devfile
2. Go to Terminal -> Run task
   You can see that for detected tasks the type of the task is used, not source (for example, shell instead of npm )
3. Try to configure a detected task - click on cog icon - the configuration should be copied to tasks.json file, but nothing is happen.

Expected behavior

• ability to configure a detected tasks
• source field is used for displaying of detected tasks
• after page refreshing Terminal -> Run Task menu action is triggered on first click

Runtime

I added to the description of the issue one more use case related to Terminal -> Run Task menu.
The video for the case is available as well.

The bug was caused by last changes in master branch of theia repo. I can not reproduce it for theia project, so some changes are required on che-theia side.

[RomanNikitenko]

I investigated the issue: the bugs related to detected tasks are caused by using 7.0.0-next version of eclipse/che-theia-endpoint-runtime for remote plugins. 7.0.0-next version doesn't contain activateByEvent logic.

So the issue is fixed by using next version of eclipse/che-theia-endpoint-runtime for remote plugins.
