The issue was that the portal shows all the release capital request that
are followed by the user (generally because, it's him that that accepted
the request). The page should only show the capital request of that the
user owns.
The bug was that trying to download the cooperator certificate or
another PDF in the interface brings an error 500. This was due to a
wrong usage of the function `get_pdf()` and also due to a error of
encoding when using `format()` python function with `{name}`. Instead I
use `"%s" % name` that works great.
It didn't use `get_pdf()` right because of an old version of mis-builder
that cause the methord `get_pdf()` to work weird. With an updated
version of mis-builder, `get_pdf()` can be used correctly.
Add a button that allow to download the cooperator certificate.
There is some access right issue for now. So for the moment the function
`send_cooperator_certificate()` in the controller is not used.
