fix(tests): remove irrelevant usage of display-=msgsep

These were just added to avoid churn when changing the default

to remove support for printing messages in default_grid later on.
This would allow things like printing error messages safely in the
middle of redraw, or a future graduation of the 'multigrid' feature.
