DW shows a conflict when overwriting a transitive dependency page

Step to reproduce:
1) Create a XAR extension with a modified page JobMacro.JobProgressMacro and with a dependency on

    <dependency>
      <groupId>org.xwiki.contrib</groupId>
      <artifactId>macro-job</artifactId>
      <version>1.1.1</version>
    </dependency>

2) Install that extension on the main wiki

Expected:

• The Jar extension of the JobMacro, and its XAR dependency is installed with the JobMacro.JobProgressMacro page overridden.

Actual Results:

• The Jar extension of the JobMacro is installed, its XAR dependency is also installed, and the installation of the JobMacro.JobProgressMacro shows a conflict between the original page and the changed one.
