[Bug] Title might be set incorrectly

[borowis]

Describe the Bug
Page title returned from /crawl, /scrape is set incorrectly in some cases.

To Reproduce
Steps to reproduce the issue:

1. Do a /scrape on https://voluitsuite.nl/post/voluit-suite-updates-5-juni-2024
2. See JSON title of the scraped page is empty
3. Open HTML of the source page and see title tag is not empty

Expected Behavior
I would expect both /scrape and /crawl return a title of the page when title tag is present

Environment (please complete the following information):

• OS: Linux
• Firecrawl Version: I'm using https://www.firecrawl.dev/app/playground so that it's easy to reproduce for you and me
• Node.js Version: NA

Additional Context
I think the problem here is that the source HTML page has both title and meta name="title" tags:

<title>voluit suite updates 5 juni 2024</title>
<meta name="title" content="voluit suite updates 5 juni 2024">

As you can see, none of them are empty so I'm not 100% sure why the problem is happening.

The potential solutions are:

• do not override title with empty meta.title value when merging dicts https://github.com/mendableai/firecrawl/blob/main/apps/api/src/scraper/scrapeURL/lib/extractMetadata.ts#L191 (easy fix);
• figure out why meta.title wasn't propagated correctly? does Firecrawl not wait long enough for the value to be set?
