Using `null` or `0` for `title` or `slug` causes issues

[joshuablum]

Bug description

It's two things essentially:

1. When a taxonomy term has the value 0 it appears empty in the listing table instead of displaying 0.
2. When creating a taxonomy term (or anything with a slug really, like an entry) typing null into the title field causes the slug field to become empty instead of showing actual null as the slug.

Brought to our attention by Ash through support. Thanks, Ash!

How to reproduce

Use 0 as a term title or null as the slug for an entry or term, for example.
