Error importing file_manager during tests.

[rnlahaye]

When trying to run the unit tests (via test/runner.sh), I get the following error:

Traceback (most recent call last):
  File "/home/rynildredeth/Happy-Hare/test/components/test_mmu_server.py", line 13, in setUp
    self.subject = MmuServer(MagicMock())
  File "/home/rynildredeth/Happy-Hare/components/mmu_server.py", line 80, in __init__
    self.setup_placeholder_processor(config)
  File "/home/rynildredeth/Happy-Hare/components/mmu_server.py", line 736, in setup_placeholder_processor
    from .file_manager import file_manager
ModuleNotFoundError: No module named 'components.file_manager'

This error occurs both on my laptop and when ssh-ed into the printer.

I'm away from my printer / system, but I believe you need to cd into the components/file_manager or at least the components directory under moonraker for this to work because that is where mmu_server.py will normally be loaded by moonraker.
