output generator tweaks

[missinglink]

in the case of this document the generated .text property is 1 Main St, United Kingdom, we should aim to have 3 components at all times where at least 2 'admin' properties are available.

this is simply to give the end-user enough information about similar results so that they can disambiguate and select the correct result.

expected: 1 Main St, Dungannon, United Kingdom
actual: : 1 Main St, United Kingdom

This will be fixed by pelias/fuzzy-tester#4 once merged :)

@orangejulius this needs to be fixed in pelias/api as it's the code to produce the human readable 'text' string
