Update git submodules
- Update MinervaNeue from branch 'master' to 937d2b48ea93b6c7c504986abdbf31dfb890288c
- Merge "On user pages, move language icon from Toolbar to Overflow menu"
- On user pages, move language icon from Toolbar to Overflow menu
The Language icon is not useful on user pages as most probably there are no translated user pages, thus there is no need to show all-time disabled Language icon.
If overflow menu is available, don't show Language switcher icon in toolbar, show it as first item in the overflow menu.
