Test: Provide a separate 'Insert snippet' command that allows the user to pick a snippet

[Tyriar]

Test for #9072, #9122, #6320, #9286:

• Windows - @DonJayamanne
• OS X - @Tyriar
• Linux - @kieferrm

There is a new command to insert snippets. Verify that

• there is a Show Snippets command in F1, and that
• it does what you expect

I'm not seeing a Show Snippets command.

On macOS.

@waderyan, @Tyriar, that's odd I just tested this on my OSX and it works! Thought I'd mention that.
@Tyriar, yes I have tested this on windows and it works as expected (thought I'd test on OSX as well, as that's my primary OS)

[Tyriar]

@DonJayamanne are you on the same commit as Wade's in the screenshot?

[DonJayamanne]

@Tyriar, identital

Works for me on both OS X and Windows.

Suggest to make labels matching Snippets (Show Snippets, Preferences: Snippets) more distinct, e.g.,:
Expand Snippet, Preferences: Edit Snippets

[waderyan]

Ok I see it now. Weird it didn't show yesterday.

@jrieken maybe this was discussed when I was on vacation but is there a reason we cannot show the list of snippets in the intellisense widget (e.g. you invoke the command via keybinding and you get a list of suggestions filtered to all snippets)? I find it better to show the snippets closer to where I am typing.
