Test suite: more robust encryption feature

All scenarios in features/encryption.feature failed on a slow system, due to the "sleep" time between “clicking the gpgapplet icon” and “sending a keypress that was supposed to be received by the gpgapplet contextual menu” was too small.

This sleep time was bumped in commit 4eff913, but really, such code is too racy:

@screen.click("GpgAppletIconNormal.png")
sleep 2
@screen.type("k")

It would be good to implement something better, like… waiting for the context menu to be displayed before sending the “k” keypress.
