Quote in term name create duplicat term

[nicolasrenard]

When you use wp_insert_term function and term has quote in his name. It creates duplicate term.

To reproduce the issue:

Create term with wp_insert_term( "test d'un terme", "your-taxonomy-slug" )

Each time the function is called a new term will be created.

Same issue in back-office :

• add termok end term'ok as name in a taxonomy
• add again termok: an error is displayed for term already exists
• add again term'ok: a new term is added with same name
