[gtksourceview] Remove unmaintained Python tests

[Sébastien Wilmet <swilmet src gnome org>]

    Remove unmaintained Python tests
    
    Nobody maintained those tests since a long time, they use deprecated
    APIs, and anyway the *.c tests are more complete. If someone really
    prefers Python, this commit can be reverted and the code ported to the
    new APIs.
