Data analysis: user org unit parameter

Hi all,

in pivot tables and data visualizar, the visualization seems to fail
when using "user org unit" as Organisation Unit if the user is
assigned to several org units. Only one of them is correctly displayed
(with name and values), and the others appear as "undefined" with no
values. This can be replicated in demo server.

Also (and just as a comment because it could be an expected
behaviour), dhis takes as "user org unit" the orgunits assigned for
data capture instead of the ones assigned for data analysis.
