Tests for git_pillar
Tests for git_pillar

Two different calls of the `ext_pillar` entry function are checked, a
direct one and one from upper in the calling stack (more integration)
The different options show the slight differences (almost side effects
between them).

A third test is included to detect infinite recursions, to avoid future
refactors that could bring them back accidentally.
