Fix a small incompatibility in ibuffer

Browse source 
Translate nil values from column functions to the empty string, so that
subsequent calls to string-width don't signal an error (Bug#26317).
* lisp/ibuffer.el (ibuffer-compile-format): If a column function returns
nil, treat it like the empty string.
