Modify all the similar Python test wrappers to set `G_DEBUG=fatal-warnings` in the environment of the program being tested, so we can catch unexpected warnings/criticals. Adding this because I noticed it was missing, not because I noticed a warning/critical was being ignored. Signed-off-by: Philip Withnall <philip@tecnocode.co.uk>
