Tests fail with python 3

[fzesch]

The tests fail with python 3. It seems as if the import of two modules (input_numper.py and dbhelper.py) does not occur properly and only works at runtime of the project. It works with Python 2, though.

My errors:

With running in PyCharm 4.5:

On command line:

The problem was, that due to the folder structure, Python expected

import lagesonum.input_number
instead of import input_number

At runtime, it looked in other paths too.
