Alexander McLin 31d7dd0317 Certain malformed queries such as "SELECT ,* FROM SomeTable" (which has an incorrect extra comma) raise "multiple statements given" error while Sqlite3 actually generates a syntax error that doesn't get returned as a raised exception. 
The same problem is encountered when executing a DDL statement such as "Create Table" more than once after the table had already been created by the first execution.

The cause is when sqlite3_prepare_v2 encounters a bad statement, it aborts the preparation, sets prep-status flag to non-zero and also sets tail? to be non-false.

The previous code ignored the prep-status flag and only checked tail? and raises "multiple statements given" exception when tail? is non-false.

The new code takes prep-status into account and extracts the actual Sqlite3 error message by evaluating get-error-message and raising it as an exception.

See Issue #1702
