SystemCatalog.getTable doesn't support escaped databases with ``

--initialization to reproduce

CREATE DATABASE `'test'`;

USE `'test'`

CREATE TABLE t1 (i int) engine=COLUMNSTORE;

CREATE TABLE test.t1 (i int) engine=COLUMNSTORE;

--Why does this not work?

CREATE TABLE `'test'`.t2 (i int) engine=COLUMNSTORE;

--But this works

CREATE TABLE `'test'`.t3 (i int);

SELECT * FROM `'test'`.t3;

SELECT * FROM `'test'`.t1;
