Unrelated Code Actions shown if multiple diagnostics exist on same line

[DudeNr33]

If multiple diagnostics exist for the same line, and at least one of the codes has a Code Action/Quick Fix available, this quick fix is shown for all codes on this line.

For example:

reimported, import-error and no-name-in-module do not have a corresponding code action. However, for all of them the quick fix Run organize imports is shown, which is registered as quick fix for ungrouped-imports only.

I stumbled across this when trying to imlement a solution for microsoft/vscode-pylint#205.

This should be filed on VS Code. We return the Code Action with the diagnostic it applies to. It is up to VS Code to show the right one for a given problem.

I will transfer this to VS Code.
