Eliminate elixir test compiler warningseliminate-elixir-test-warnings

Eliminates the following:

warning: variable "epoch" is unused (if the variable is not meant to be used, prefix it with an underscore)
  src/couchdb/test/elixir/test/replication_test.exs:1756: ReplicationTest.seq_to_shards/1

warning: variable "uuid" is unused (if the variable is not meant to be used, prefix it with an underscore)
  src/couchdb/test/elixir/test/replication_test.exs:1756: ReplicationTest.seq_to_shards/1

warning: variable "string" is unused (if the variable is not meant to be used, prefix it with an underscore)
  src/couchdb/test/elixir/test/utf8_test.exs:32: UTF8Test."test UTF8 support"/1

warning: variable "repeated_view_offset_test_fun" does not exist and is being expanded to "repeated_view_offset_test_fun()", please use parentheses to remove the ambiguity or change the variable name
  src/couchdb/test/elixir/test/view_offsets_test.exs:63: ViewOffsetTest."test repeated view offsets"/1
