The update share tests only checked that the share returned by
"update()" had the expected values. However, as "update()" returns the
same share that was given as a parameter the tests were not really
verifying that the values were updated in the database.
In a similar way, the test that checked that a password was removed did
not set a password first, so even if the database returned null it could
be simply returning the default value for the share; a password must be
set first to ensure that it is removed.
Besides that, a typo was fixed too that made the checks on the original
share instead of on the one returned by "update()"; right now it is the
same share, so the change makes no difference, but it is how the check
should be done anyway.
