Added a few test case for User (save/delete)

Added: test case for delete
Added: test case for save
Removed: todo from testBind

I hope this one is working straight out of the box this time unlike last/first one.

is there some doc or something on how to setup a envioment to run the tests and so on my self to ensure it is working before making a pull request ?

I don't think http://docs.joomla.org/Joomla_CodeSniffer is that... ? as it seems to only be related to coding syntax.

Note, i assume that if i add the user for delete test in to the xml that will be the same as if it is in database ?

-Thanks
