Multiple small changes/fixes to the hr_recruitment module to provide
a better base for later improvements.
The linkedin recruitment source is only added by default to new records,
existing records remain unchanged.
For the google map in the email template, since it requires an API_Key and
only a minority of companies will get this key, it was decided that
it is better to remove it from the template.
Now that linkedin is added to job positions by default, deleting a
job position currently does not delete the related linkedin source.
So after removing 10 job positions, there are still 10 linked in
source in the database. This commit fixes that.
Add three additionnal utm_sources.
Add linkedin as a source job to demo job position to be consistent with no-demo
data db.
