[FIX] web_planner: links to modules form
[FIX] web_planner: links to modules form

This partially reverts rev. 84ade6a8617e38c0afdd156e404f59a943feedca

In this specific part of the code, the goal wasn't
to check if the module was part of the installed modules,
but if the module was part the "known" modules, in order
to jump on its form.

Besides, as this link is most of the time used
to install the according module, it's quite dummy
to search it within the installed modules.

Before this revision, trying to click on the "Install" links
in the planners linked to an empty module form, instead
of the according module form.
