Update bitstream-ordering.js

There is a bad JQuery selector in the following code. This causes a submit to take place each time an up or down arrow is clicked. It is difficult to see the error in the javascript console because the submit takes place immediately. 

Due to the page refresh delay, this is confusing to users when a large number of bitstreams are present. 

Note that "$^=" is not a valid selector.

Update bitstream-ordering.js

Found an additional scenario in which a javascript error occurs while re-ordering bitstreams.

Create an item with 3 original bitstreams.

Go to the edit bitstream screen and hit the down arrow on the second item.  An error will be thrown revealing a row without an id attribute.

[DS-2195] Ensure that a found Group's TableRow is typed.

DatabaseManager.querySingle returns an untyped TableRow.  We can't use
querySingleTable because the row contains columns not found in the
required type.  Just force the row to have a type anyway, since it
does contain all of the columns required for that type.  Otherwise the
Group is not update()able.
