Title: Add "path with an exceptional situatuion" test

Implement a unit test which tests the situation, when a user's input is
a complex path that raises an execption. For example, the following
input raises NameError: `cd :toplevel`, `cd 1/2/hi`. We should ensure
that after the second expression our current binding is still
`:toplevel`.
