Hello Felix Singer, build bot (Jenkins), Thomas Heijligen, Edward O'Callaghan, Angel Pons,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

tests: Add unit test for initialisation with NULL programmer param

Programmer param can be NULL and this is a valid case which can
be covered by unit test.

`run_lifecycle` needs an adjustment to handle NULL as programmer
param, which is also included in the patch.
