remove_index missed quote_table_name

in lib/active_record/connection_adapters/abstract/schema_statements.rb
there is a missing quote_table_name in line 286 (def remove_index):

execute "DROP INDEX #{quote_column_name(index_name(table_name,
options))} ON #{table_name}"

so my "keys" table can get an index with "add_index" but can't remove
it (without tweaking)

replacing it to

execute "DROP INDEX #{quote_column_name(index_name(table_name,
options))} ON #{quote_table_name(table_name)}"

would help (and would be logical).

Best regards

You'll want to add a test showing the failing case, and succeeding after your change. A table name of `index` or `on` or something.
