[mypy]: make mypy and pre-commit run mypy results differ #2414
Description
On the current master running make mypy yields the following list of errors for me:
$ mypy --version
mypy 0.800
$ mypy -p telegram

while running pre-commit run mypy (with a small irrelevant change, so it isn't just skipped) yields:
$ pre-commit run mypy
mypy.....................................................................Failed

As you can see, the two pre-commit errors are there aswell and fixing/ignoring them makes them go away in both cases.
Ignoring the other errors makes make mypy return without errors, but then the pre-commit version complains about unnecessary "type: ignore" comments.
I have not touched any configs and the mypy version should be identical, my python version is 3.8.5.
