323e72a50c [poincare/matrix_layout] Remove columns with backspace 
Allow removing empty columns with backspace, the same way one can remove
empty rows. This allows deleting the internal columns that are not
automatically deleted.

7184202a6e [poincare/matrix_layout] Keep median rows and columns 
Empty columns and rows are only removed automatically when they are the
last row/column. This way, the user can edit a median row/column without
the matrix collapsing.

Léa Saviot
5df60e946a [poincare] shallowBeautify can modify the reduction context 
UnitConvert must set UnitConversion to None, otherwise the unit asked
for in the conversion might get changed after being properly set in
UnitConvert::shallowBeautify.

d789e8da97 [poincare] In Multiplication::shallowBeautify, when extracting the unit, 
reduce without changing the unit in order to extract the right unit.

This fixes the following bug: simplify "πππ23*_cK"
