What's in this PR?

Improve the ActiveChecker class:

• Internal UrlGenerator instance was removed, instead url() helper from Laravel is used now.
• Internal Request instance was removed, instead request() helper from Laravel is used now.
• Improve the logic of the class.

Improve the HrefFilter class:

• Internal UrlGenerator instance was removed, instead url() helper from Laravel is used now.
• Improve the internal filter logic.

Tests were modified to adapt to the previous improvements:

• The HrefFilter tests were separated into a different test class.
• Since the ActiveChecker and HrefFilter constructor methods were changed, most of the test were adapted.

Checklist

• I tested these changes.
