Cancel Query Button Doesn't Stop Query Execution

[sivan-koren]

• MSSQL Extension Version: 1.10.0
• VSCode Version: 1.52.1
• OS Version: Windows 10 20H2 (build 19042.746)

Steps to Reproduce:

1. Start a query.
2. Click the Cancel Query button.

A message appears to state that no query is running. However, a query is in fact running.

Running an infinite query:

declare @i int
while (1=1)
set @i = 1

shows that it can be cancelled easily without any issue, this is probably related to the new version of STS that was added since this bug was filed. This was fixed by microsoft/sqltoolsservice#1246
