buildingNumber is 0, 00, 000 in some locales

[micheh]

In pull request #737 the default and en_US Address data provider was updated to not generate a building number 0, 00 or 000 anymore.
However, the bug still exists in multiple locales, e.g. de_CH or de_AT.

I think the fix should be applied to all locales, not only the default one and en_US.
