Escape table name in when building a select statement with row id

Summary:
When a KDbQuerySchema has a table name or alias that is a reserved SQL
keyword, and the alsoRetrieveRecordId statement option is set to true,
KDbNativeStatementBuilder constructed an incorrect statement.

For instance, if trying to create a SELECT statement in SQLite of a
table named “table” with a single “id column, the generated query was:

SELECT [id], table.OID FROM [table] ORDER BY [id]

The execution if that query generated an error due to the unescaped
table keyword. With this commit, the generated query is:

SELECT [id], [table].OID FROM [table] ORDER BY [id]
