Autoimport breaks when enabling the plugin

Describe the bug Having the pydantic-pycharm-plugin enabled breaks autoimports.

To Reproduce Steps to reproduce the behavior:

1. Install the pydantic plugin and enable it
2. Create a simple file main.py with the content:

from typing import Optional
from pydantic import BaseModel


class Item(BaseModel):
    name: str
    description: Optional[str] = Field()
    price: float
    tax: Optional[float] = None

1. Navigate the caret between Field and ().
2. ctrl+space+space or alt+enter
3. No pydantic import suggested

1. Disable pydantic plugin
2. Try the same:

Expected behavior Autoimports should work.

Environments (please complete the following information):

• IDE: PyCharm Professional 2021.1 (Edit: Tested in 201.1.1 as well. Same issue)
• OS: Red Hat Enterprise Linux release 8.3 (Ootpa)
• Pydantic Versio: 1.8.1
• Plugin version: 0.3.0

Additional context I’ve tried recreating the environment, clearing and invalidating cache.

I’ll check out both pipx and your poetry plugin, thank you!!

Also, You are sponsoring me!!

I listened to episode 313 of talkpython.fm. Creator of pydantic gave you some nice words and in the end of the episode he encourages not only sponsoring the huge packages, but also those who make those packages awesome. This is one of them. 😊 So my pleasure.
