superfluous (wrong!) method in code example

[Sammeeey]

In step 8 of part 7 is a wrong piece of code.
It looks like this:

updateSelectedLocation(location: HousingLocation) { } searchHousingLocations() {}

But it should be this:

updateSelectedLocation(location: HousingLocation) { }

This is tightly connected to (but not the same as) #12
