test sql table name
Closes #9393 

simple test for tables names that need to be quoted.
This is related to issue [here](https://github.com/pydata/pandas/issues/9393) that is fixed in current master.

@dashesy The sql tests are here: https://github.com/pydata/pandas/blob/master/pandas/io/tests/test_sql.py
 yes, tests are looking good now! (and for fixing the test :-))

When do you get the `AttributeError: '_TestSQLApi' object has no attribute 'connect'` errors? What do you run exactly?

Further, could you squash the commits into one (for merging the PR)? (`git rebase -i upstream/master`) If you have questions about it, just ask!
 @jorisvandenbossche  I test in Eclipse/PyDev by running the module as a test unit.
 @dashesy Thanks for the test!

When working on the sql code, I just run the `test_sql.py` file (there is a main function in the end) and that works for me.
