GBL --> Aardvark Migrator Refactors

[the-codetrane]

Problem

v1_aardvark_migrator was failing when RESOURCE_CLASS_MAP[@v1_hash['dc_type_s'] and RESOURCE_TYPE_MAP[@v1_hash['layer_geom_type_s'] returned nil when gsub was called (lib/geo_combine/migrators/v1_aardvark_migrator.rb:54 and lib/geo_combine/migrators/v1_aardvark_migrator.rb:55)

Solution

• add save-nav method (&) to gsub
• make guard clause for is_part_of explicit (will handle nil)
