**Describe the bug**
Join fails if table names contain some special symbols (e.g. '/').

**How to reproduce**
* Which ClickHouse server version to use
version 20.11.4
* Which interface to use, if matters
* Non-default settings, if any
* `CREATE TABLE` statements for all tables involved
create table "/t0" (a Int64, b Int64) engine = MergeTree() partition by a order by a;
create table "/t1" (a Int64, b Int64) engine = MergeTree() partition by a order by a;
* Sample data for all these tables
insert into "/t0" values (0, 0);
insert into "/t1" values (0, 1);
* Queries to run that lead to unexpected result
select * from "/t0" join "/t1" using a
**Expected behavior**
A clear and concise description of what you expected to happen.

**Error message and/or stacktrace**

Received exception from server (version 20.11.4):
Code: 62. DB::Exception: Received from localhost:9000. DB::Exception: Syntax error (table or subquery or table function): failed at position 16 ('/'): /t1) as /t1. Expected one of: SELECT subquery, compound identifier, identifier, element of expression with optional alias, list of elements, function, table, table function, subquery or list of joined tables, table or subquery or table function.

**Additional context**

When I rename tables with "t0" and "t1" everything works fine. It looks like ClickHouse rewrites query somehow and uses table names without quotes.

{
    if (storage)
    {
        const ColumnsDescription & storage_columns = metadata_snapshot->getColumns();
        tables_with_columns.emplace_back(DatabaseAndTableWithAlias{}, storage_columns.getOrdinary());
        auto & table = tables_with_columns.back();
        table.addHiddenColumns(storage_columns.getMaterialized());
        table.addHiddenColumns(storage_columns.getAliases());
        table.addHiddenColumns(storage->getVirtuals());
    }
    else
        tables_with_columns.emplace_back(DatabaseAndTableWithAlias{}, source_header.getNamesAndTypesList());
}
