Subject: [PATCH] updateMap will be automatically triggered on page reload 
 (#570)

* feat: a page reload will automatically trigger updateMap

This commit adds a mounted lifecycle hook to the MainMenu component in order to update the map when the page is reloaded or refreshed.

* fix: prevent reusing of the tileCacheHash instead of using updateMap
