fix(route53): Avoided useless usage of regions for tag fetching

It appears as though you can get all the tags without problem from any
region (I've tested this from a bunch of different regions and they
all worked out properly with no problem). This results in an enormous
time save: on one AWS account, the Route53 portion of process-account
went from taking ~1m30s to ~8s
