[FIX] hr_expense: select the right employee for an expense created with alias

Current behavior:
When trying to create an expense using alias, if there's several `hr.employee` linked to a user, it select the first one instead of this with the right company

Steps to reproduce the error :
- Create different employee's profiles for a same user
- Put the default one on the user's profile (don't put the first that you created because it will select the first for the expense)
- Try to send an email to the expense's alias and check at the logs

After this commit:
The right employee (this one in the default company) will be selected and no error will be triggered
