Garbage in code sample

[robertoaceves]

On https://codelabs.developers.google.com/introduction-to-angular#6, the code sample has garbage after the method definition.

Add a new method called updateSelection with a parameter called location and with a type of HousingLocation.

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

This part should not be included --> searchHousingLocations() {}.
