Do not use an action when naming an event that will be fired to the
delegate. Instead of saying what the delegate should do or will do, just
say what event happened. So in this case, say to the delegate that the
instructions import link on the Bookmarks Bar was clicked.

BUG=None
TEST=have zero bookmarks in your Bookmarks Bar, so you can see the link there,
click on it to show the import dialog. No regressions should be observed.
