Mate Lakat 178b8402d9 Fix aggregates test with multi host setup
Fixes bug 1046222.

The aggregate exercise assumed that you have only one compute node, thus
it failed with syntax error for two hosts. With this fix, the exercise
will pick the first compute host, and use that for the tests.

# This script demonstrates how to use host aggregates:
# * Create an Aggregate
# * Updating Aggregate details
# * Testing Aggregate metadata
# * Testing Aggregate delete
# * Testing General Aggregates (https://blueprints.launchpad.net/nova/+spec/general-host-aggregates)
# * Testing add/remove hosts (with one host)
