[gtk] testinfobar: Add simple test of :visible/:revealed

[Daniel Boles <dboles src gnome org>]

commit 6bb1f0dbf36672eaae7173a58cae31a6e780d15a

    testinfobar: Add simple test of :visible/:revealed
    
    This exists merely to prove that, having added :revealed, show() and
    hide() now work reliably, as does set_revealed() for the animated case.
