Ripasso is not working with git submodule

[nachevn]

My pass folder contains only submodule from git. My assumtion is, cause of this ripasso fails to start with the message:
The password store is backed by a git repository, but there is passwords there that's not in git. Please add them, otherwise they might get lost.
Unfortunately I wasn't able to find anything in the issues or something regarding ripasso and the usage of git submodule.

OS: Arch Linux
ripasso build from the master branch (sha:c10e163) with https://github.com/cortex/ripasso/blob/master/BUILD_INSTRUCTIONS.md

What I expected:
Ripasso starting correctly

What happened:
The password store is backed by a git repository, but there is passwords there that's not in git. Please add them, otherwise they might get lost.

This is a great feature request, I hadn't thought that people might use submodules in their password repo.
