When running the render test for EEVEE-Next the command printed on
the report to update the reference images was incorrect. In stead of
displaying
`BLENDER_TEST_UPDATE=1 ctest -R eevee_next` it displayed
`BLENDER_TEST_UPDATE=1 ctest -R eevee next`.
The cause of this is that the title of the report is used to create
the command. EEVEE-Next has a space in its title which generates
an incorrect command.
A quick fix would be to replace spaces with underscores. But it would
be better to fix this more clearly by adding an attribute containing the
engine name.
This PR adds a `set_engine_name` method to the Report class. By
default the engine name is set based on the title.
