Complexity: 3

Tests #66574.

Create a simple extension that contributes a task, a problem matcher, and a problem pattern (starting point below). Run VS Code with the extension, but don't activate it. The problem matcher should show up as a completion suggestion for the problemMatcher task property if you create a tasks.json task. Disable the extension without activating it and verify that the contributed problem matcher is no longer in the tasks.json suggestions. Verify that the task is not available if you execute the Run Task command. Finally, re-enable the extension and verify that it's contributions are available again.
