db_connection_name other than default

[hvoers]

In my config.yml I have:
plugins: DBIC: interch: schema_class: Interchange6::Schema dsn: "..." ... etc ...
So I want to point the session engine to that schema name:

`engines:
session:
DBIC:
db_connection_name: interch # connection name from DBIC plugin

session: DBIC
`
I get this error:

[apptestname:49759] error @2016-08-16 22:16:52> Route exception: Exception caught in 'core.app.before_request' filter: Hook error: The schema default is not configured at /usr/local/lib/perl5/site_perl/DBICx/Sugar.pm line 52.

I think this happens at the moment of session creation.

What do you think?

Extra info: I also use a BEGIN block in the main app with:

DBICx::Sugar::config( config->{plugins}->{DBIC} );

to do some initial stuff.

When I remove that line I get the error:

[apptestname:62848] error @2016-08-17 02:12:50> Route exception: Exception caught in 'core.app.before_request' filter: Hook error: Unable to create a new session: could not find a config.yml or config.yaml file at /usr/local/lib/perl5/site_perl/Dancer2/Session/DBIC.pm line 384.

It must be session creation calling "schema()" with no config.

I have made a PR ironcamel/DBICx-Sugar#3
to get some extra tools to debug this.
