Add the app-dir to the python path when exporting the schema

[Matt343]

Description

The export-schema command was inconsistent with the debug server command, as it did not include the app-dir argument that modifies the PYTHONPATH. Without this argument, the command couldn't find local modules as the current working directory was not added to the path.
