Fix GH-11384: Resolve property before model reflection to avoid recursion#11385

… recursion
When a POM contains ${project.url} in the <url> field and also defines
a property named 'project.url', Maven was incorrectly attempting to
resolve the expression via model reflection first, which would return
the same ${project.url} value, causing a recursive variable reference
error.
This fix changes the interpolation resolution order to check model
properties before prefixed model reflection. This allows properties
like 'project.url' to be resolved from the <properties> section before
attempting to use reflection on the model object.
The new resolution order is:
1. basedir
2. build.timestamp
3. user properties
4. model properties (moved up from position 5)
5. prefixed model reflection (moved down from position 3)
6. system properties
7. environment variables
8. unprefixed model reflection
This change is consistent with the approach used for MNG-8469, which
established that explicit property definitions should take precedence
over model field reflection.
Fixes apache#11384
Remove incorrect constructor with version parameter. AbstractMavenIntegrationTestCase uses a no-argument constructor and version constraints are handled differently in the new test framework.

Description
Fixes #11384
When a POM contains
${project.url}in the<url>field and also defines a property namedproject.url, Maven was incorrectly attempting to resolve the expression via model reflection first, which would return the same${project.url}value, causing a recursive variable reference error.This pattern is used by projects like slack-sdk-parent.
Solution
This fix changes the interpolation resolution order to check model properties before prefixed model reflection. This allows properties like
project.urlto be resolved from the<properties>section before attempting to use reflection on the model object.New Resolution Order
Rationale
This change is consistent with the approach used for MNG-8469, which established that explicit property definitions should take precedence over model field reflection.
