fix: do not attempt to parse non-existent FB pages

Browse Source 
When user enters something invalid (like number 123), it wuold still hit
FB webpage and return HTML. I do simple detection by looking at title
when it attempts to parse the DOM directly. When it contains "Content
Not Found", it is skipped.

Non-existent web pages cannot be parsed by using LDJSON parser and
looking at null data.
