Bug in print_pdf method when the url is a viewer page of a pdf file (e.g., Chrome PDF Viewer).

[joao-voltarelli]

Describe the bug

• In headless mode, when a path is not passed, 2 pdf files are being created, one with the page content and the other empty. When the path is passed as a parameter, only an empty file is saved.
• In headfull mode, the file is not saved in the path passed by parameter, it is always saved in the default path.

Expected behavior

• The file must be saved correctly in the path that is passed by the parameter or in the default path, regardless of the execution mode.

Steps to Reproduce

• Access a url which is actually a view of a pdf file, for example: http://www.africau.edu/images/default/sample.pdf
• Try using print_pdf method passing a path by parameter, in headless and headfull mode.

Possible Solution

• Maybe be able to collect the page title, which is used as the name to save the file.
• Always save the file in the default path and then manipulate to move to the path passed by the user, if that's the case.

My Platform

• OS Version: Windows 10 Home - 21H1
• Python Version: 3.10.1
• Packages Version: botcity-framework-web: 0.3.1
