{id} not parsed in URI on initial save

[chasegiunta]

Description

Upon creating a new entry in sections with {id} in their URI (issues/{id}), the twig won't be parsed (at least in my case) - leaving the result in the uri column in the element_sites table as issues.

This leads to inevitable "Could not generate a unique URI based on the URI format." upon trying to save new entries.

This also only applies on initial saves/entry creation. Re-saving the entry will save the correct URI issues/12

Steps to reproduce

1. Create new channel section with the title "Issues" and entry URI format as issues/{id}
2. Save new blank entry in that section.
3. Check element_sites table to see resulting URI
4. Try to create new entry. Observe "Could not generate a unique URI based on the URI format."
5. Re-save first entry.
