Prospero update prepare command adds .installation/.git folder to original EAP. This is a regression, so I set blocker priority.

Example:

./jboss-eap-installation-manager.sh update prepare --dir=/tmp/originalServer --repositories=file:/path/to/jboss-eap-8.1.0.Beta-runtime-maven-repository/maven-repository/ --candidate-dir=/tmp/updatedServer --local-cache=/tmp/tmp_local_repo

/tmp/originalServer should not be updated.
