[Inconsistency in scraperwiki.sqlite.get_var before save_var.

[tlevine]

@scraperdragon posted this to the dummy repository issue tracker, so I copy it here.

On Scraperwiki Classic:

import scraperwiki
print scraperwiki.sqlite.get_var('kitten')
returns None.

On boxes:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/src/scraperwiki-local/scraperwiki/sqlite.py", line 66, in get_var
return dt.get_var(name)
File "/usr/local/lib/python2.7/dist-packages/src/dumptruck/dumptruck/dumptruck.py", line 273, in get_var
data = self.execute(u'SELECT * FROM %s WHEREname= ?' % vt, [key], commit = False)
File "/usr/local/lib/python2.7/dist-packages/src/dumptruck/dumptruck/dumptruck.py", line 107, in execute
self.cursor.execute(sql, *args)
