fix(toolbar): Wrong placement of last icon when there is a menu

[touficbatache]

Fixes and closes #1026 @yeelan0319

[kfranqueiro]

Should we have an example of this added to the toolbar demos? Maybe addressable separately but IIUC there's nothing OOTB that demonstrates the issue/fix right now.

[lynnmercier]

@kfranqueiro is right, we should add an example of this in our demos directory.

[touficbatache]

I can do that, so from what I unrderstood I should add an example with the menu, correct?

[kfranqueiro]

Yes, specifically what I had in mind was add another example to the toolbar demos that contains a menu on the last icon. It should then be easy to test with/without the CSS change to see the fix.

I made the necessary changes! @yeelan0319 @kfranqueiro
