[WebSQL] Wrong error code returned for constraint error

[fatso83]

According to W3 WebDatabase spec the SqlError code for Constraint errors is 6. Node+PhantomJS returns 1.

{"code":1,"message":"constraint failed"}

This specific error was caused on INSERTing a duplicate entry into a table. All browsers return { code : 6, ...} .

I've got the similar error saying {"code":1,"message":"could not execute statement (1555 UNIQUE constraint failed: TABLE_NAME.COLUMN_NAME)"}.
PhantomJS should return code:6 (CONSTRAINT_ERR) rather than 1.

Due to our very limited maintenance capacity (see #14541 for more details), we need to prioritize our development focus on other tasks. Therefore, this issue will be automatically closed. In the future, if we see the need to attend to this issue again, then it will be reopened. Thank you for your contribution!
