Issue Type: Bug

I'm having an issue with the git sync (which uses --tags). The project I work on relies on certain tags in order to do some deployments to QA servers. The tags are always the same name but they're constantly pointing to different refs so I get an error in VSCode when I try to sync. Output log:

> git pull --tags origin features/LITE-1050-more-options-for-showinfo-param
> git show HEAD:imports/startup/client/scripts/components/sections-layout-cards.component.js
From github.com:mapmelabs/mapme-lite
 * branch              features/LITE-1050-more-options-for-showinfo-param -> FETCH_HEAD
 ! [rejected]          qa2        -> qa2  (would clobber existing tag)
> git show HEAD:imports/startup/client/scripts/components/sections-layout-cards.component.js

In order to "fix" it, I need to run git pull --tags -f and VSCode sync works until the tags change again. Since I don't need to pull tags, is there any way to instruct VSCode not to use --tags when it pulls? I already looked in the settings but haven't found anything.
This has been a big drawback for me lately. Thanks.
