Stop trying to format import lines based on package name to please isort

[Joonalai]

Expected behaviour
It should be acceptable, if pre-commit does some isort formatting during initial commit. CI tests should not check if isort fails with those imports.

Current behaviour
plugin.py tries to format import lines based on package name.

Describe alternatives you've considered
Use tempalte tag formatting with every import that has package name.
