Debug loftover and invalid regex syntax in the validator service

We should extend AddressVerificationTest to cover the problematic address.

The (\d*|\d*\/\d*) was not really capturing the whole house numbers that contain slash, reversing the order to get that as well: (\d*\/\d+|\d+).

When adding the problematic address to the test, I saw that the or fix (|| > |) actually broke that (seems like the broken syntax was producing correct results for this case). But then I wasn't sure if we should try to solve it with a different regex, so I just added another if block.

I also added some trimming for the street and expanded the test cases quite a bit.

Merged.
