Views menu item resets position

Menu order does not persist if you add a 2nd View.

Workaround seems unlikely to be discovered by most users.

Steps provided by @harings_rob for reproducing the issue (#2468713: Internal/custom menu links force-reset to the top of their menus on cache rebuild) still apply if you add multiple Views.

Steps:

Have a menu with some item.
Add a view, add it to the menu.

Add a 2nd view; add it to the menu.

Edit the menu and drag it to another place.
Flush cache
Views menu item resets position. Show as expanded also resets*

*Show as expanded did not appear to be an issue.

A few other details seem worth noting:

1. when exporting the configuration for the second View, no 'weight' attribute appears under the Menu section (no mention of weight at all)
2. if you deliberately set a weight within the View UI, it sticks even after cache is cleared
3. if you deliberately set a weight within the Menu UI, it does not stick beyond first save of the menu changes
