At the moment, the share_network database API which the web
API layer interacts with directly does not have any checking
for project_id which means that a user has the ability to run
operations against any other share_network if they have the ID.
This patch implements the usage of project_only in the database
query which ensures that administrators still have the behaviour
of getting any share network they want, but users can only pull
up those which are part of their context/authenticated project.
This patch also adjusts a few other tests due to the fact that
the existing tests would run a lot of inserts with a different
project_id than the context, which is not allowed in this new
API behaviour. Therefore, the instances that involved projects
different than the context were converted to elevated ones.
There was also an instance where they were being created with a
project_id that did not match the fake context, therefore the
context was adjusted accordingly as well.
