Retrieve real plugin jar instead of static resource jar

Some plugins, most notably GWT UI plugins, have intermediate artifacts
that are called <plugin-name>-static.jar. Usually those artifacts are
retrieved on the first position and artifact searching algorithm hasn't
filtered them out. This results in annoying troubleshooting sessions
because gerrit listing those plugins as installed, but given that
those jars are just GWT resources nothing is actually working.

The following plugins were affected:

* reviewers-static.jar
* review-strategy-static.jar
* menuextender-static.jar
