Tab Context not saved after closing the browser

[timzul-1002]

Precise recipe to reproduce the issue

• Enable option Settings > Buffer Settings > Restore session on startup
• open new tab in custom context (create new context if needed)
• open any URL to your liking
• close and then open the browser again
• open buffer list and check which context is used for your tab opened with context
• the tab context is now 'default'

This functionality has been stripped in the latest Nyxt and will be reimplemented from scratch with a new architecture.
