Restore locales before calling test assertions

[glensc]

Restore locales before calling assertions otherwise sql will be broken:

From #34 (comment):

seems enabling locale tests by installing needed locales, brings more trouble than needed.

the tests are not run in proper isolation, i.e global resource like locale must be restored after a test, and that is not performed, neither are tests run in isolation (i think phpunit 3.7 does not even support that), and sql queries are written with very bad style, resulting syntax error as numeric value value formatted with comma according to locale rules, gets parsed as two values in sql.

2) Zend_Db_Table_Select_MysqliTest::testSelectWhereOr
Zend_Db_Exception: SQL error for "INSERT INTO `zfprice` (`product_id`, `price_name`, `price_total`) VALUES (1, 'Price 1', 200,45)": Column count doesn't match value count at row 1

NOTE: fixing the DB layer to be independent on locale is a legacy that zf1 carries and can't be fixed.

#49 has been merged, so can rebase now to see that pdo tests will start to fail because they are not locale aware.

I'm unable to reproduce the "locales break float and create sql injection' problem.
This should have been the job that failed, but it didn't:

but I guess it's not that important anymore, as the code passes now.

I'm very glad that you sorted this issue out

@glensc Is it safe to merge now? It looks good to me.
