Title: Fix modifyinteraction

Make sure lastPixel_ is set before calling handleMouseAtPixel.

This fixes the issue I've been having: define modify interaction and features to it, this without having the mouse hover the map once. If I mouse hovered the map before adding the features to the modify interaction, then it would be fine since lastPixel_ would be set.
