Assembly plugin does not inherit configuration/execution from parent

This used to work in 2.2-beta-5, but both 2.2 and 2.2.1 seem to ignore attached descriptors in "mvn install"

Sample project to follow.

This works:

mvn -Dass.vers=2.2-beta-5 install -Prc

This does not:

mvn -Dass.vers=2.2.1 install -Prc

If you compare the ouput from the two runs, you will see that the following is missing from 2.2.1:

[INFO] [assembly:attached

]
[INFO] Reading assembly descriptor: src/assembly/bin.xml
[INFO] Reading assembly descriptor: src/assembly/src.xml

[INFO] Building zip: D:\maven-tests\assembly-bug\target\assembly-bug-1.0-SNAPSHOT-src.zip

Apache Commons cannot use 2.2 or 2.2.1 as a result of this bug
