[BUGFIX] fix NavDrawer to force href update of menu items

[romanwozniak]

In #30, NavDrawer component was updated to use EuiTreeView instead of EuiListGroup. EuiTreeView doesn't support href property, so menu navigation was implemented with onClick property and then navigate to the desired destination.

However, this doesn't work properly, because mlp applications are deployed as separate single page apps, so the destination utl could be outside of the application's state (i.e. if user clicks on Merlin menu item from the Turing app, then this page doesn't exist in Turing's router). To solve this, the page should be forcefully refreshed and this is achieved with update of window.location.href.

On top of this, I've updated dependencies and fixed some of rollup warnings (such as circular dependency).

I'm curious about this line. At first, I thought it should be a condition expression for the ternary operator, but it seems you are assigning value to window.location.href by using one =. Is it another JS magic that I don't know? Please enlighten me.

Which part is magical here? :) yeah, I'm assigning a value (conditional) to window.location.href and with that you can sort of programatically trigger a click on a link with assigned href value.
Trick is that navigate comes from @reach/router and it navigates inside a single page app (SPA) (without triggering a full refresh of the page), so I need to emulate a click on a link to completely refresh the page (so another SPA can be downloaded)
