"Fix all occurrences of a code issue..." lists different issues then in the problems tab.

## Issue Description ##
I'm using .editorconfig to disable some rules. This works fine for the problems reported, however when I run any of the "Fix all occurrences of a code issue..." from the command palette it sees and will apply disabled rules as valid options.
## Steps to Reproduce ##
1. Enable Roslyn analyzers and editor config support.
2. Set a dotnet_diagnostic severity to none.
3. Bring up an example file that should trigger the rule.
4. Open the command palette and run a "Fix all occurrences of a code issue..." command. It should bring up a list that includes the disabled rule.

## Expected Behavior ##
I expect that the disabled rules do not appear or apply.

## Actual Behavior ##
The disabled rules do appear and will apply. This is particularly annoying for "fix all issues".

## Logs ##

### OmniSharp log ###
N/a - but it will list that it "fixing" the disabled rules in the log.

### C# log ###
N/a
