`copy_to` is adding extra `"` to table name #272

I am creating a Trino table from a select statement on another Trino table. It renders the wrong sql script which adds extra " wrapping the table name.

httr::set_config(
  httr::config(
    httpauth=1,
    userpwd='user:password',
    ssl_verifypeer=0
  )
)

con = DBI::dbConnect(
  drv = RPresto::Presto(),
  host="https://trinohost",
  port=8443,
  user=user,
  password=password,
  catalog="hive",
  schema=my_schema,
  bigint="numeric"
)

person <- dplyr::tbl(con, "person")

dplyr::copy_to(dest = con, df = person, name = "person_new")

The sql it renders:

CREATE TABLE """person_new""" AS SELECT * FROM "person"

The table_name got created is "person_new" instead of person. 

dplyr::tbl(con,'person')  # failed
dplyr::tbl(con,'"person_new"') # succeed

Seems a compatibility issue with dbplyr 2.5.0. It works fine after I downgrade dbplyr to 2.4.0

This was supposed to be solved by #265. However commit #265 is broken due to #274.
