task terminal is not reused

[akosyakov]

It's reproducible with theia repo:

• start from sources
• from npm scripts view run textmage-grammars test
• run again when task is finished
• a new terminal is created

Also if you don't wait for termination but try to run again, click return in notificaiont then it fails alltogether with error notification.

Here you see 2 terminals for very same taks and an error notification:

I believe it is a known issue that terminals created from tasks cannot be re-used?

• @theia/task Doesn't run task, creates new terminal #5825
• [task] disallow running identical tasks #5269 (comment)

@vince-fugnitto I see i thought it was already addressed. :(
