fix(backend): fix ProjectAssigneeInline has no attribute inlines error

[c0rydoras]

this should make it so projects can be created via django admin again

[winged]

Not sure this is the right way to fix it - other admin Inlines don't have the attribute either. If you looked at the exception, what was the context of the call site?

[c0rydoras]

I don't remember, steps to reproduce:

1. Navigate to timed instance
2. /admin
3. Create project
4. Receive error

[c0rydoras]

I don't think this is the right way to fix this, but it could be a temporary fix
