Indexed DB: Remove vendor prefix removal from tests

LayoutTests/storage/indexeddb/key-generator-expected.txt

 Test IndexedDB's key generator behavior.
 
 On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

 Verify that each object store has an independent key generator.
