Update schema.rst

The error is that sqlite3 needs escaping on the database column 'text' in the line:
text text not null
so that it becomes:
'text' text not null

The example on mitsuhiko/flask is correct and helped me detecting the mistake.
The example does not execute

With the inclusion of the app.run we now are able to execute the program, it would be great if we'd have even more detailed docs available for the examples
