Subject: unittests: T2995: vyos_dict_search() must return None on non-existing
 keys

The current wversion unfortunately will raise a KeyError:

>>> data = {}
>>> vyos_dict_search('foo', data)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/vyos/util.py", line 685, in vyos_dict_search
    return dict[path]
KeyError: 'foo'
