Update Insights to GrantVis when signposting to maps

[mariongalley]

The tests around missing location information signpost to the map in Insights, but this should be GrantVis as the tool has now moved and changed name

As designed - this was left on purpose, as it mentioned things like IMD and other insights, but we could easily change it
