Nil street when addr has no street type and apt number has directional letter

[micahtessler]

Here is a sample of addresses that have nil for street when parsed

The pattern is the street has no type PENNSYLVANIA instead of PENNSYLVANIA AVE and the apt number ends in a directional: 6E instead of 6B

note that adding a street type like AVE will find the correct street, or an apt number that doesn't end in a directional like 3G will cause the street name to be parsed correctly
