Setup should display error when database user does not have permissions to create tables

The Setup doesn't display an error message when the user does not have permissions to create tables in the database. Instead it simply goes ahead to the next step to create a user and fails with the following exception:

Cause:
org.springframework.jdbc.BadSqlGrammarException: Bad SQL grammar [] in task 'Hibernate operation'; nested exception is java.sql.SQLException: Invalid object name 'os_user'.
at org.springframework.jdbc.support.SQLStateSQLExceptionTranslator.translate(SQLStateSQLExceptionTranslator.java:85)
caused by: java.sql.SQLException: Invalid object name 'os_user'.

We should catch the lack of permissions earlier and display an appropriate error message.
