Crash fix: prevent crash in MapLocationModel::reload

Browse source 
Commit 0c38754916 introduced a
bug in MapLocationModel::reload() by setting an entry in the
name-to-location map before the location was initialized.

Move the setting of the map entry back where it was before:
after the assignment of the location variable.

Moreover, define the location variable directly on allocation
of the location to avoid thus bugs in the future.

Why did we not get a "might be used unitialized" warning
anyway?
