Doesn't sync if on previously repo was unaccessible

[maslovw]

Steps to reproduce:

• disconnect from VPN (I guess simple internet disconnect would do too)
• change any file
• call git-auto-sync sync
• • it should give an error accessing remote repository
• connect VPN
• try git-auto-sync sync

Expect: retry: git add; git commit; git pull; git push
Observed: nothing to commit -> stops even though local is 1 commit ahead of remote

➜  git-auto-sync --version
git-auto-sync version 1.5

➜  git-auto-sync sync
2024/04/30 16:23:23 exit status 128: Command: git fetch origin
StdOut:
StdErr: ssh: Could not resolve hostname gerrit.int.COMPANY.com: nodename nor servname provided, or not known
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
