Prevented Xlib sequence errors in xcb plugin.

Prevent Xlib errors of the form
"Xlib: sequence lost (0x2716a > 0x1717c) in reply type 0x11!" from
being printed. We know the cause of these is because we're manually
calling the XESetWireToEvent handlers since those are not handled by
XCB, and this confuses Xlib since it's then seeing events with old
sequence numbers. We simply set the sequence number to the latest
sequence number and the errors go away.
