Get correct URL for all cases

[schorschii]

Description

I noticed that the URL is not correctly found out in all cases.

Example URL: https://example.com/dir1/test

In this example, "dir1" is a real existing directory on the server, and "test" is a additional string appended and handled by the index.php script in this dir (via Apache rewrite). In this case, the MatomoTracker will track "/test" instead of "/dir1/test". This change fixes the behavior to correctly track "/dir1/test".

Review

• Functional review done
• Potential edge cases thought about (behaviour of the code with strange input, with strange internal state or possible interactions with other Matomo subsystems)
• Usability review done (is anything maybe unclear or think about anything that would cause people to reach out to support)
• Security review done
• Wording review done
• Code review done
• Tests were added if useful/possible
• Reviewed for breaking changes
