Partially revert 3025e0630de2b9ced3d0aadd1513cb0e1c93b159

This commit did the "right" thing by implementing Qt mode semantics
as intended, but for unknown reasons the profile is not properly
cleared on close-file anymore. This code is so convoluted that there
is not point in fighting it at the moment. Revert to remove-rows
instead of reset-model.
