nit: use the WebString constructor that takes in a char?

It doesn't seem to have a convenient ctor for this particular case, I'll keep as
is in this CL.

 
   const int64_t transaction_id = 1;
   const int64_t object_store_id = 2;
 
   StrictMock<MockWebIDBCallbacks> callbacks;
   EXPECT_CALL(callbacks, onError(_)).Times(1);
 
   WebIDBDatabaseImpl database_impl(nullptr,
                                    base::ThreadTaskRunnerHandle::Get());
   database_impl.max_put_value_size_ = kMaxValueSizeForTesting;
   database_impl.put(transaction_id, object_store_id, value, web_blob_info, key,
                     blink::WebIDBPutModeAddOrUpdate, &callbacks,
                     WebVector<long long>(), WebVector<WebVector<WebIDBKey>>());
 }
