Remove extra space from schema dumper output

[sharipov-ru]

Scenic dumps db/schema.rb with redundant space symbol before sql_definition parameter:

Example 1:

create_view "old_users",  sql_definition: <<-SQL
    SELECT users.id,
    users.name,
    users.age,
    users.created_at,
    users.updated_at
   FROM users
  WHERE (users.age > 100);
SQL

Example 2 with materialized view:

create_view "young_users", materialized: true,  sql_definition: <<-SQL
    SELECT users.id,
    users.name,
    users.age,
    users.created_at,
    users.updated_at
   FROM users
  WHERE (users.age < 100);
SQL

This PR fixes it, so that there are no extra spaces before sql_definition and linters like rubocop don't complain here anymore.

After:

Example 1:

create_view "old_users", sql_definition: <<-SQL
    SELECT users.id,
    users.name,
    users.age,
    users.created_at,
    users.updated_at
   FROM users
  WHERE (users.age > 100);
SQL

Example 2 with materialized view:

create_view "young_users", materialized: true, sql_definition: <<-SQL
    SELECT users.id,
    users.name,
    users.age,
    users.created_at,
    users.updated_at
   FROM users
  WHERE (users.age < 100);
SQL
