Missing info if objects are contained in .pack file

[AndrejZbin]

Some objects may be packed in .git/objects/pack/*.pack file, which may cause some properties like tag, commitMessage, ... to be null. Looking at the source code, these .pack files are not used at all.

This is how I produced the issue, some steps are probably redundant:

1. Clone existing repo from GitLab repository
2. Create tag for the last commit in master
3. Create a new branch with some commits
4. Create merge request and accept it
5. Create tag for the last commit in master
6. git fetch, git pull

You can also reproduce it by running git gc. Running git unpack-objects after fixes it.

Here is specification of the git .pack format:
