PulseAudio has devices that are None

Fixes #8797

Fixes #8992

element can be None if there was a error while calling Gst.ElementFactory.make()

Prefer the error message text over the error code

fetchone() returns None when nothing is found
len(None) yields a TypeError

Add the SHIFT + PAGE_UP keypress
Fix catching mouse scroll UP on some systems

For MUCs on the blacklist we do a deduplication not depending on
stanza-id

This patch is only for current Prosody 0.10 stable and the mod_mam_muc
module which does not add stanza-id to the messages.

This can be removed once Prosody 0.11 hits or the module is updated

Dont ship cacerts, use certifi on Windows

Dont trigger resizes on notify::position, because the absolut
handle position changes also on window resizes, but the relative handle
position doesnt change.

Instead we use the notify::position event now to save the new position
to the config file and use left button release event (release of the handle after dragging)
and the window maximize/minimize event to trigger resizes in all controls

This fixes also fixes a issue where a previously hidden roster was shown again
if a new tab was opened.

Gajim stopped to properly restore roster and dialogs windows positions
after restart with more than one monitor attached.

Gajim saves the absolute window positions, i.e. based on the total screen size
of all monitors attached. Despite Gtk deprecated Gdk.Screen.width() and height(),
we cannot just use width() and height() for one monitor, as recommended.
We still need the total screen size, which was the base for saving the positions.
