[IMP] project: add default personnal stage to user

Currently, when a db is loaded without demo data, or that a user has no
task assigned and no personnal stage, the view 'My tasks' is empty. The
purpose of this commit is to assign default personnal stage to a user in
these case to ease the understanding of new user of what the view can be
used for.

This commit :
- add default personnal stage to user the first time he clicks on the
'My tasks' menu if the user has no personnal stage and no task are assigned
to him.
