Create unexisting anOrbeonApp from OrbeonBuilder left bpmEnvironment in nil

[bruno.buzzi]

Context: BpmFlow + Orbeon
Steps:

1. Create new form for an unexisting OrbeonApplication (inside Orbeon Builder)
2. Publish 1)

BpmOrbeonFormBuilderSaveApi>>getAffectedProcessesBy: 
anOrbeonPublishedFormDefinition application bpmEnvironment --> nil

When anOrbeonApplication is created inside Orbeon Builder it does not have BpmEnvironment.
It is recommended in the manuals create everything inside BpmFlow but the user can create OrbeonApplication inside Orbeon Builder.
