fix: init script not creating models REFS #24

for the longest period of time i had been wondering what i was doing wrong
where what is in the comments of the ticket works but then formalising it
here did not work https://github.com/anomaly/lab-python-server/issues/24\#issuecomment-1246172651

i was initially suspecting asyncio related issues but it turns out that
the models of the application were never imported into the context when
the create_all was called, which i accidentally had in context when i
prototyped the calls in the comment

there are notes on the initialise method as to why the models are in context

this also fixes the typo in the poetry command
