Ouch, I missed it and pushed the similar fix:

https://lists.tarantool.org/pipermail/tarantool-patches/2020-October/020242.html

Difference: it wraps a (possibly empty) tag name into quotes and adds
`|| true` to ignore `git tag -d ""` non-zero exit code.

I guess it is better than assume that `git tad -d` will not fail (I
didn't found anything about this case in the manual page).
