Subject: [PATCH] Fix obscure bug when checking restore prices of duplicate
 domain names (#968)

* Fix obscure bug when checking restore prices of duplicate domain names

There were instances of "java.lang.IllegalArgumentException: Multiple entries
with same key" in the logs, caused by attempting to construct an ImmutableMap
containing duplicate keys. It turns out this was happening in the domain check
flow when the following conditions were all simultaneously met:

1. The older v06 fee extension is used
2. The same domain name is being queried multiple times in a single check
   command (which is valid per the spec but doesn't actually make any sense)
3. Said domain exists
4. The cost of a restore (an uncommon operation) is being checked

When all of those conditions were met, an error was being thrown when the
dupe-containing list of domain names was used as the keys of a new Map. This
fixes that bug by calling .distinct() first.

Give enough registrars enough typewriters ...
