Nuxeo IDE / SDK cannot run correctly with a custom database template

If the template "postgresql" is added to the nuxeo-sdk.conf file such as:

nuxeo.templates=default,postgresql,sdk

then the generated nuxeo.xml file is still using the derby configuration, for instance:

<Resource name="jdbc/nxrelations-default-jena" auth="Container"
type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000"
driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
url="jdbc:derby:/opt/nuxeo-dm-5.4.3-SNAPSHOT-tomcat/nxserver/data/derby/nuxeo;create=true" />

Instead of:

<Resource name="jdbc/nxrelations-default-jena" auth="Container"
type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://localhost:5432/nuxeo"
username="nuxeo" password="nuxeo" />

This can probably be fixed by making the IDE run the `bin/nuxeoctl configure` command first to generate a nuxeo.xml file that reflects the templates aggregation from the configuration of the original `bin/nuxeo.conf` file.
