Application.activate not emitted when opening files.

[Victor Aurélio Santos <victoraur santos gmail com>]

A Application with flags = GLib.ApplicationFlags.HANDLES_OPEN when
launched without any files it does the normal start, and `activate`
signal is emitted, but when opening files the `activate` signal didn't
gets emitted ? even when it's the first instance of application.

Is this the default behavior ? or am i doing something wrong?
If it's the default behavior, how and where should i do application's
basic things like creating windows, setting-up basic things etc...
