Repair of repo cloned from 4.3 and update to 4.4 does not update submodules

[georgik]

Scenario:

• Install 4.3 by offline installer
• update git to master

Observed behaviour: Python is referencing to 4.3 while using env 4.4 and submodules are also not updated. Start of idf.py command fails on missing python-socketio<5

Workaround:

• run online installer, pick the repo and let the installer repair references
• on command line type: git submodule update --init --recursive

Workaround:

• run install.bat
• run: git submodule update --init --recursive
• close the terminal
• open new terminal

Workaround:

• run online installer and make fresh install of ESP-IDF to a new directory
