Remove version from name of Ant-built jar

Previously, the project version was included in the name of the
Ant-built jar and the integration test assumed that there would be a
single jar in the output directory. This assumption did not hold true
if the project's version had changed and the project had been built
again without a clean. This resulted in two jars, one for the previous
version and one for the current version, in the output directory. This
caused a test failure.

This commit updates the build.xml to remove the version from the name
of the Ant-built jar and updates the integration test to find it.

Closes gh-22782
