Title: fix: rare crash placing new bases

Crashes can occur in two cases:
1) If a mouseover triggers between base being named and
BuildNewBaseState destructor call.
2) If a mouseover triggers between confirm new base cancellation and
BuildNewBaseState destructor call.

Solution is to swap between globeHover handler and an empty handler as
necessary.
