Tests: Fix failing maya automatic test

[kalisp]

Changelog Description

Caused by tripping on failed import of Max submit to deadline, because of Max library, issue of Pyblish imports handling. That file shouldn't be imported at all in perfect world.

Additional info

Was causing # Error: pyblish.plugin : Skipped: "submit_max_deadline" (No module named 'pymxs') # error

This is a bit band aid fix, but everything else would be much more elaborate.

Testing notes:

1. run C:\test_build\tests\integration\hosts\maya\test_publish_in_maya.py

Think this should be fixed in the host integration, similar to #5954

[kalisp]

I tried that, but couldn't figure all places I need to move imports around.

[tokejepsen]

How about we just focus on this plugin and these imports?

https://github.com/ynput/OpenPype/blob/develop/openpype/modules/deadline/plugins/publish/submit_max_deadline.py#L19-L26

Its the Deadline modules' plugins folder that is the culprit of all these import issues. Ideally that plugins folder should have a folder per host or register individual plugins rather than the whole folder.
