Title: Add listener for null values or voids returned by controllers

With this commit, returning nothing (implicitly) or null (explicitly)
results in the creation of an empty view model, just like this happens
with conversion from an array into a view model.

Code is updated and bootstrap file changed. Tests are included too.
