Revert "ci(circle): Remove loop in bash release script"

This reverts commit ed058cb.

Issue #81 has probably been caused by CircleCI feature called "auto-cancel
redundant builds". When release script pushed a new commit to master branch build was cancelled, because default branch
for this repository is `develop`, and builds are not cancelled
automatically with this feature only for default branches.
