[FIX] base: invisible="context.get(...)" takes priority only if True

This is an oversight in odoo/odoo#100130

A modifier set with `context.get('...')`,
for instance
`invisible="context.get('sign_directly_without_mail',False)"`
takes priority on attrs
only if the result of `context.get('...')` isn't falsy

e.g.
https://github.com/odoo/enterprise/blob/1a4e4fafe4fc78dab0aad7ab6241a6f4a7be317a/sign/wizard/sign_send_request_views.xml#L64

should return
- `modifiers="{'invisible': [['is_user_signer', '=', false]]}"`
  with `context.get('sign_directly_without_mail') == False`
- `modifiers="{'invisible': true}"`
  with `context.get('sign_directly_without_mail') == True`

closes odoo/odoo#101813
