clang-format: [JS] don't break comments before any '{'
Summary:
Previously, clang-format would avoid breaking before the first `{`
found, but then happily break before subsequent '{'s on the line. This
change fixes that by looking for the first location that has no opening
curly, if any.
This fixes the original commit by correcting the loop condition.
